Jew of the Week: Lynn Margulis

The Rebel Evolutionist

Lynn Petra Alexander (1938-2011) was born in Chicago to a prominent Jewish (and passionately-Zionist) family. She got accepted to the University of Chicago when she was just 15 years old, and graduated with a BA four years later. That same year, she married (former Jew of the Week) Carl Sagan, then on his way to becoming a world-renowned scientist himself. She then went to the University of Wisconsin and earned her Master’s in genetics and zoology, followed by a PhD from UC Berkeley. Around that time, she divorced Carl Sagan and later married another scientist, Thomas Margulis. Although she divorced him as well, she kept the last name and is best known today as Lynn Margulis. In 1966, she became a biology professor at the University of Boston and remained there until 1988, when she became Distinguished Professor of Biology and Geosciences at the University of Massachusetts. Her 1967 paper “On the Origin of Mitosing Cells” was initially rejected by fifteen journals and stirred a great deal of controversy before being confirmed experimentally in 1978. Much of her research (and the opposition to it) was based on demonstrating major flaws within Darwin’s evolutionary theory. She would say that “Natural selection eliminates and maybe maintains, but it doesn’t create.” Margulis offered one hypothesis of her own, endosymbiosis, now a widely-accepted theory in biology and a key mechanism of evolution. Margulis also co-authored the first paper on the now-famous Gaia hypothesis regarding the intricate interactions between living things and the planet. Margulis worked tirelessly to the last days of her life. She co-authored another big (and controversial) paper in 2009—at the age of 71! Margulis has been called a “scientific rebel” and won countless awards, including a National Medal of Science from President Bill Clinton and a NASA Public Service Award for Astrobiology. She also has 15 honourary doctorates and was elected to the National Academy of Sciences. In 2002, she was ranked among the 50 most important women in science.

Jews of the Week: Levi Strauss and Jacob Davis

Inventors of Your Favourite Pants

Jacob Davis

Jakobs Jufess (1831-1908) was born in Riga, Latvia. He became a tailor before immigrating to the US at age 23. Upon arriving in New York, he changed his name to Jacob Davis and opened up a tailor shop. Over the next 15 years, he moved all across North America trying to make a living, spending time in Maine, California, Nevada, and British Columbia, working as a tobacco salesman, gold miner, and brewer. By 1869, Davis settled in Reno, Nevada and opened another tailor shop. His primary merchandise was originally tents, horse blankets, and wagon covers. To make his stuff stronger and more durable, he started using the toughest cotton denim he could find, which happened to come from a small dry goods store in San Francisco called Levi Strauss & Co.

Levi Strauss, the name behind Levi’s jeans.

Levi Strauss (1829-1902) was born in Buttenheim, Germany. When he was 18 years old, his family immigrated to the US, joining two older brothers that had settled in New York some years earlier. The brothers had set up a dry goods shop, and Levi went on to open a new store location in Louisville, Kentucky. During the California Gold Rush, the family saw opportunity in the West and opened another branch in San Francisco. Strauss headed that branch (together with his sister’s brother, David Stern), importing from his brothers in the East and selling high-quality merchandise at his Levi Strauss & Co. shop. He became very wealthy, and built San Francisco’s first synagogue, Temple Emanu-El. Strauss gave generously to many charities, too, and his Levi Strauss Foundation donated to multiple orphanages and universities (including UC Berkeley). In 1871, Strauss received an offer from Jacob Davis to go into business together. Davis had designed a new type of work pants using blue denim and copper rivets to make the material extra strong. The first set of such “jeans” was custom-tailored for a lumberjack. Before long, everyone wanted a pair, and Davis couldn’t keep up with demand. Strauss helped Davis get the proper patents, and the two partnered up. To make his jeans distinct, Davis soon started to sew the back pockets with the now-ubiquitous orange double-stitch. Meanwhile, Strauss built a large jeans factory in San Francisco and Davis moved there to run the plant. Davis worked at the plant for the rest of his life, outfitting every miner, railroad worker, and cowboy with “Levi’s jeans”, his special pants. The modern jeans that Davis and Strauss brought to the world grew rapidly in popularity, first in the workforce, then among teenagers and “greasers” in the 50s and 60s, and today being the most popular type of pants in the world.

Jews of the Week: Waksman and Schatz

Selman Waksman

Selman Abraham Waksman (1888-1973) was born near Kiev to Jewish-Russian parents. At 22, he immigrated to the U.S. and began his studies at Rutgers University, where he got a Masters in Science before getting his Ph.D. in biology at UC Berkeley. He then headed back to Rutgers to take over the soil microbiology lab, focusing on the study of soil organisms and decomposition. Building on the work of previous scientists, Waksman soon found that bacterial substances could be used to fight bacterial infections. He shifted his lab’s focus towards finding “antibiotics” – a term which he coined. Over the next couple of decades, his lab discovered a dozen antibiotic compounds.

Albert Schatz

Most important of these was streptomycin, discovered by Waksman’s student Albert Israel Schatz (1920-2005). Schatz also came from Jewish-Russian lineage and originally wanted to be a farmer. He studied soil microbiology, and after serving in a military hospital during World War II, decided to research treatments for tuberculosis. Working in Waksman’s lab, Schatz discovered and named “streptomycin”, which would become one of the most important antibiotics in history, and is still found on the World Health Organization’s List of Essential Medicines. Schatz made no profit from his discovery, giving up his rights to the drug so that it could be distributed as widely and cheaply to as many people as possible. Unfortunately, he was never given the credit he deserved, with the Nobel prize going only to Waksman in 1952. Both biologists continued their contributions to science, and were decorated with many awards. Waksman also developed microbe-resistant paint for ships, enzyme-enhanced detergents, and a compound to prevent fungal infections of vineyards. He wrote over 400 papers and published 28 books. Meanwhile, Schatz campaigned against the fluoridation of water, proposed new theories for tooth decay and the extinction of dinosaurs, and published over 700 papers and 3 textbooks. Both were ultimately credited for streptomycin, which The New York Times ranked among the Top 10 discoveries of the 20th century.
