The genius of Luther Burbank, father of the most famous potato in the world

Luther Burbank created some of the world’s most commercially successful fruits and vegetables, all from his Santa Rosa, California farm.

Editor’s note: This article is part of an ongoing series about lesser-known Californians who have made a significant impact on the state. California Characters seeks to bring their stories to light, highlighting voices and achievements that history has often overlooked. Through this series, we aim to celebrate the individuals who have shaped California in ways both big and small, ensuring their contributions are recognized and remembered.

The Los Angeles Times recently ran a review of fast-food french fries that caused a stir because the writer placed fries made at Californiaโ€™s beloved In-N-Out burger somewhere near the bottom. This infuriated the stateโ€™s rabid fan base for what is arguably one of the best burger joints in America. (Raises hand in support). But one interesting side story, the ideal kind of story we cover here, is this: if it were not for the work of one Californian farmer, we would likely not have french fries at all, or at least not as we know them today.ย

That is because most french fries today are made with a particular strain of potato –  the Russet Burbank – that exists largely because of one man: Luther Burbank. Burbank is a little-known Californian (part of an ongoing series) whose contributions to science, in particular botany, have had an outsized impact on much of the fresh produce we consume today. 

Burbank is a towering figure in horticulture, credited with creating the science of modern plant breeding. For decades in the late 19th, early 20th centuries, his experimental farm in Santa Rosa, California, was famous throughout the world for the stunning variety of new fruit and vegetable varieties that emerged from the farmโ€™s fertile soil.

Born in 1849 in Lancaster, Massachusetts, Burbank came to California in 1875, buying a four-acre plot of land to start a nursery and garden in order to breed edible crops. While not a trained scientist, Burbank had a preternatural knack for identifying desirable characteristics in plants, which he selected for through an arduous, time-consuming, and oftentimes brilliantly intuitive series of techniques that led to the creation of some of our most cherished strains of fruits and vegetables. 

Over the course of his 55-year career, Burbank developed more than 800 new strains and varieties of plants, including flowers, grains, grasses, vegetables, cacti, and fruits. These include 113 varieties of plums, 20 of which remain commercially valuable, especially in California and South Africa. He also developed 10 commercial varieties of berries (including the oxymoronically-named white blackberry) as well as more than 50 varieties of lilies

Amazingly, Burbank was able to achieve all this without direct knowledge of plant genetics, pioneered by the Augustinian friar Gregor Mendel in what is now the Czech Republic in the mid-1800s (and whose papers on growing pea plants were brought to light in 1901, long after his death in 1884). Burbankโ€™s lack of precise record-keeping and somewhat unorthodox — some would say sloppy — record-keeping, has led some modern scientists to criticize his credentials. Purdue University professor Jules Janick, wrote that “Burbank cannot be considered a scientist in the academic sense.”

That said, Burbankโ€™s innovations in Santa Rosa were revolutionary and garnered him worldwide attention, as well as financial support from benefactors like Andrew Carnegie, who supported Burbank because he believed the work was of great potential benefit to humanity. 

Burbank perfected techniques in common use today such as grafting, hybridization, and cross-breeding. At the time, his efforts resulted in large yield increases for numerous edible species in the United States in the early 20th century. 

But perhaps Burbankโ€™s most lasting achievement was the Russet Burbank potato, which first came on the scene around 1902. Burbank bred the new stain from an unusual “seedball” he found on his farm, which came from a strain called Early Rose. Burbank planted the seeds, chose the most select fruits and further hybridized those. Soon, he had a wonderfully robust and hearty potato that he could sell.  

This large, brown-skinned, fleshy-white tuber is now the world’s predominant potato in food processing. The Russet Burbank is ideal for baking, mashing, and french fries. It is now grown predominantly in Idaho, the top potato-growing state in the US, where the variety makes up more than 55% of the stateโ€™s potato production. 

Burbank came up with the Russet Burbank potato to help with the devastating situation in Ireland following the Irish potato famine. His aim was to help “revive the country’s leading crop” due to the fact that it is โ€œLate blight-resistantโ€. Late blight disease destroyed potato crops across Europe and led to a devastating famine in Ireland because the country was so dependent on potatoes as a common foodstuff. Unfortunately, Burbank did not patent the Russet Burbank because plant tubers, of which the potato is one, were not granted patents in the United States. 

But the Russet Burbank was such a hearty strain, and so nutritious and flavorful (though some disagree), that it became the potato of choice for many grocery stores and restaurants. This did not happen automatically, but took about two decades to catch on. In fact, in 1930, the Russet Burbank accounted for just 4% of potatoes in the US. But things would quickly change with the advent of frozen french fries in the 1940s and the subsequent emergence of fast-food restaurants like McDonaldโ€™s in the 1950s. The Russet Burbank was perfectly suited for french fries and remains the worldโ€™s most popular potato by a long shot.  

Unfortunately, Luther Burbank had a dark side, especially by modern mores. He believed in eugenics, the idea that human beings should be selectively bred like produce. He was a member of a national eugenicist group, which promoted anti-miscegenation laws, segregation, involuntary sterilization, and other discrimination by race.

Luther Burbank died after a heart attack and gastrointestinal illness in 1926. His name is known in certain regions of California, in and around Santa Rosa, although if you asked the average person who he was, few would be able to say. The Luther Burbank Home and Gardens, in downtown Santa Rosa, are designated as a National Historic Landmark.

A war is brewing over lithium mining near Death Valley

Lithium. It is one of the world’s most valuable elements, allowing batteries to be more powerful and longer-lasting than ever before. Right now, most lithium is mined in the high deserts of South America, but a new battle is being waged between battery companies and environmentalists over whether to mine lithium in Panamint Valley in California, right on the edge of Death Valley. There are strong arguments to be made that having a large domestic source of lithium is key to a carbon-free future, but some are saying that mining would potentially despoil one of California’s most treasured natural areas.

The LA Times has a story on how Australia-based firm Battery Mineral Resources Ltd. is seeking permission to drill four exploratory wells beneath the valley floor to see if enough lithium is there to make a mine economically viable.

The comeback of Mark Twain’s frogs

Red-Legged Frog Release.

The California red-legged frog is said to be the species featured in Twain’s short story “The Celebrated Jumping Frog of Calaveras County.”

They began to disappear decades ago due to disease and habitat destruction, but a recent program to reintroduce them back in Yosemite Valley is seeing some progress. The program reintroduced about 4,000 California red-legged frog eggs and tadpoles and 500 adult frogs, into Yosemite and near the Merced River. For the first time, biologists have found eggs from the reintroduced frogs. That’s great news, given the rapidly declining state of frogs around the globe. The recent IPBES UN report says that more than 40 percent of amphibian species around the world are threatened with extinction.

Science of traffic jams

Traffic jams. They are the bane of California drivers. But what causes them, and is there any way to lessen their severity? Mathematicians have developed all sorts of models to better understand how traffic forms, and some of them has been helpful to improve flow. For example, extra-long freeway entry lanes (take a drive on Highway 110, the old Route 66, which has very short entry lanes, to see what I’m talking about.) An interesting story in Nautilus examines how fluid models are being used to better predict and reduce traffic jams. It’s complicated, but you will learn about the jamiton. And we’re not holding our breath that things will improve in places like LA anytime soon.

Scallop eyes surprise scientists

Wikipedia

Many people know that scallops have eyes, blue ones, in fact. But their eyes function a bit differently than our own. As light enters into the scallop eye, it goes through the pupil and then a lens. Interestingly, the scallop has two retinas, and when the light hits them it strikes a crystal mirror made of guanine at the back of the eye. 

A study in Current Biology looks at two species: the bay scallop Argopecten irradians and the sea scallop Placopecten magellanicus, and reveals that scallops have a novel way of focusing light. They have no irises like ours and so they use their pupils to dilate and contract, and this, along with changes to the curvature of the cornea, improves resolution and forms crisper images. Vision is such an amazingly complex ability, yet it has likely evolved 50 times among animals, a process called convergent evolution. There are several scallop species in California, and the next time you are diving and see one, remember that it probably sees you right back.

Reducing cow burps with seaweed

UC Davis

You’ve seen Harris Ranch on I5? Did you know that California is a major producer of beef and dairy. Cows produce prodigious amounts of methane, one of the most potent greenhouse gases. In fact, methane is 30 times worse than CO2. Meanwhile, more than halfย of all methane emissions in California come from the burps, farts, and exhalations of livestock. And belches are the worst, accounting for roughly 95% of the methane released into the environment. Worldwide, livestock accounts for 16% of our greenhouse gas emissions. A fascinating new approach at Scripps Institution of Oceanography proposes using seaweed as cow feed. Scripps notes that “just a small amount ofย Asparagopsisย seaweed to cattle feed can dramatically reduce methane emissions from dairy cows by more than 50 percent”.

Something’s happening here. Sea life around California is changing.

Hakai Magazine

This time of year, it is normal to see whales – grays and humpbacks among them – migrating north to cooler climes and nutrient-rich waters in Alaska. But it’s not normal for them to hang around for a long time, nor is it normal to see them frolicking together in San Francisco Bay.

โ€œThis was like opening a door temporarily for southern species to move northward,โ€ Eric Sanford, a professor of biological sciences at the University of California at Davisโ€™s Bodega Marine Laboratory told the Washington Post.

Welcome to the new normal. The new hotter normal. As climate change brings floods, higher sea levels, drought and more severe storms, it is also leading to strange behavior in the animal world. Species that once lived much further south around Mexico are now finding their way into California waters, surprising and also concerning scientists who say that these migrations are a sign of bad things to come.

The whales are likely hanging around, say scientists, because they are hungry, meaning that something is happening to their food supplies.

But we’ve also witnessed other species on the coast that are rarely or never before seen. A yellow-bellied sea snake washed up on Newport Beach. A very rare olive Ridley sea turtle was seen near Capistrano Beach. And who can forget the huge hoodwinker sunfish that made headlines last month.

It is likely just the beginning of a massive change in our local ecosystems, and the consequences could be especially severe for the species that already live here, whose habitats are changing. Case in point, the massive die off of starfish caused by an infectious wasting disease that reduces these beautiful creatures to mush. A new report published in the journal Science Advances lays much of the blame on the changing climate. Check out the video by Hakai Magazine.

Behold the magnificent murre

Creative Commons: Didier Descouens

During the California gold rush, the rocky volcanic Farallon Islands off the coast of San Francisco became a kind of war zone, as groups of men battled over a precious resource: birds eggs. In particular, the eggs of the common murre, a sharp-beaked black and white bird whose eggs are curiously conical. Scientists speculate the reason for the rather odd shape is that evolution designed them to roll in circles, instead of tumbling into the sea.

The marine science magazine Hakai has a great piece on the common murre and the work being done to better understand their biology and evolutionary history. One recently discovered fact is that common murre females lay eggs with different colors and reflectance, allowing the parent murres to specifically identify it as their own offspring. Wow! Johnny, that IS you!

But back to the so-called eggs wars of the late 1850s. Smithsonian magazine has a wonderful story by Paige Blankenbuehler about the conflict, which arose because so many people had come to California in search of gold, and of course they had to eat. Food production, in some cases, could not keep up with demand. Certain foods, in particular, chicken eggs, became so scarce that enterprising poachers went to the Farallones to collect the eggs for sale to hungry 49ers. The competition to collect them became so fierce that “brawls broke out constantly between rival gangs, ranging in brutality from threats and shell-throwing to stabbings and shootouts.”

Yikes. All over some colorful, conical eggs.

Big Bear Lake’s adorable new Eaglets

Eagle cam Friends of Big Bear Valley

Though indigenous to California, bald eagles are not often seen around the state, at least near our big cities. It used to be common to see them, but in the early 1970s, after the bald eagle numbers declined dramatically due to impacts from insecticides, the bird was listed as an endangered species. In fact, in the 80s, there were fewer than 30 nesting pairs in the state. Today, they’ve recovered somewhat and can occasionally be seen at lakes, reservoirs, rivers, and some rangelands and coastal wetlands. 

But now, you can see two baby bald eagles that just hatched at Big Bear Lake. A live cam put up by Friends of Big Bear Valley allows you to ogle them live from the comfort of your computer screen or device.

Going to prison for killing a rare fish

Death Valley National Park

In April 2016, three drunk men broke into a fenced-in limestone cavern at Death Valley National Park, home of the endangered Devils Hole pupfish, one of the rarest fish in the world. The fish has evolved in extreme desert conditions and has been isolated for tens of thousands of years, and this is one of the only places they live. Thinking it was a nice night for a swim, one of the men plunged into the warm pool where, it so happened, the pupfish were breeding. One of the fish died.

The men were caught (an excellent tale told by High Country News), and Trenton Sargent, the guy who jumped into the pool, pleaded guilty to violating the Endangered Species Act, destruction of federal property, and possessing a firearm while a felon. He was sentenced to a year in prison.

Folks, leave endangered species alone. And don’t trespass on or destroy federal property.

An oral history of the Keck Observatory

One of the amazing lesser-known repositories of the history of science is the vast oral history project at the California Institute of Technology.

Since 1978, the esteemed scientific school has been collecting the stories of some of its most distinguished names, many of them Nobel Prize winners. Others, hardly known at all, have made huge contributions to human health and they deserve greater attention.

A recent oral history from the archive is actually an edited compendium of interviews that tells the story of the Keck Observatory. The Keck Observatory near the summit of Mauna Kea Hawaii consists of two telescopes peering into the heavens from 13,600 ft. above sea level. A major advance of the telescope (and some of the details of how are covered in the oral history) was the ability to operate using 36 hexagonal segments as a single, contiguous mirror. Each telescope weighs 300 tons and operates with nanometer precision. Scientists using the Keck have made major discoveries about exoplanets, star formation, and dark matter.

There’s a ton of great information about the telescope and the discoveries being made at the Keck site.

An end to California’s magnificent mountain lions?

Credit: US National Park Service

Two mountain lion populations in Southern California face a real threat of extinction if an effort is not made to protect their environment and create so-called “wildlife corridors” through the city’s developed areas, a new study warns.

Thestudy published in the journal Ecologist Applications that examined DNA from the lion’s blood and tissue samples from the 1990s to 2016, shows that the species could soon experience “inbreeding depression”, a term used to describe when genetic diversity has declined to the point that the species’ future existence is called into question. A similar issue occurred with Florida panthers.

The greatest danger facing the magnificent cats remains being struck by a motor vehicle. Mountain lion advocates are hoping for approval for a $60 million Liberty Canyon Wildlife Crossing over Highway 101 connecting the Santa Monica Mountains to the Sierra Madre Mountain Range. It’s possible construction of the corridor could begin as early as 2022.

Hydraulic mining’s efficient destruction

Credit: Eastman Collection of the University of California, Davis

When most of us think of the California gold rush, we picture gold panners hunched over a stream, or shoveling dirt into long, wooden sluices, all in an effort to reveal so-called color, shiny pieces of malleable yellow metal that brought thousands of people to California. But in the later years of the gold rush, in the 1860s and 70s, hydraulic mining was the dominant method of extracting gold from the hills.

Hydraulic mining used high-pressure jets of water to dislodge rocky material or move sediment. The jets were so powerful that men were killed by the force of the water from 200 feet away. It was extremely efficient, but also incredibly damaging to the environment. By the time hydraulic mining was banned in 1884, according to John McPhee’s Assembling California, hydraulic mining was responsible for removing 13 billion cubic yards of the Sierras.

The disappearance of Yosemite’s Lyell glacier

Greg Stock is a geologist at Yosemite National Park where, for the last decade, he has documented the decline of the park’s Lyell glacier. The glacier sits on Mount Lyell, the tallest peak in Yosemite National Park (13,120 feet). An 1883 photograph (above) shows the glacier spread across 13 million square feet. Current photographs reveal mostly bedrock now, a sad tale of global warming and the rapid loss of glacial ice in California.

Daniel Duane of California Sunday Magazine visited the remains of the glacier and followed along with Stock as he continued a 135-year effort to map and understand the glacier’s decline. It’s a wonderfully well-wrought tale, but like so many stories in these warming days, it’s a depressing one.

Descanso Gardensโ€™ rare collection of dinosaur-era plants

Cycad plant

In 2014, La Canada Flintridge residents Katia and Frederick Elsea called the city’s Descanso Gardens with an odd proposal: would the famous horticultural center take their collection of over 180 cycads rare cycads, a fern-like plant from the days of the dinosaurs?

The garden said yes, and now those plants are part of Descanso Gardensโ€™ Ancient Forest. Cycads are so old, in fact, they appear in fossils from over 280 million years ago. That makes them far older than flowers. (Flowering plants first appeared in the Jurassic period about 175 million years ago.) In the Ancient Forest, there are also redwoods, tree ferns and ginkgoes, all โ€œliving fossilsโ€ from a long past era.

Descanso is also the location of North America’s largest collection of Camellias, a genus found in eastern and southern Asia, from the Himalayas to Japan and Indonesia.  At the gardens, there are also some of the oldest oak trees in the city, dating back to Spanish colonial times, beneath which you can take a stroll or simply hang out and enjoy the shade.

As the planet warms, get ready for more mosquitos

Global warming promises to bring more than just sea level rise, more severe storms, and destructive wildfires. According to researchers at Stanford University, a change in the earth’s temperatures is also likely to increase the range and numbers of biting insects like mosquitos, that seek out warmer, wetter climes. California itself could be impacted, with the insects pushing north from tropical climes.

Mosquitoes transmit numerous harmful diseases including malaria, dengue fever, chikungunya and West Nile virus. It’s estimated that they kill about 1 million people a year.

The Los Angeles Fire Department (LAFD) has begun a program to use drones to find and respond to fires. It’s potentially a very big deal, given that the 2018 wildfire season was the deadliest and most destructive on record in California. Some 8,527 fires burned across 1,893,913 acres last year. That’s larger than the state of Delaware. It was the largest burned area ever recorded in a fire season, according to the California Department of Forestry and Fire Protection.

The agency is partnering with Chinese drone-maker DJI, in what is being called one of the first partnerships between a drone company and a major fire agency. The LAFD will use drones equipped with both visual and thermal imaging cameras that will provide real-time video and data transmission to incident commanders.
