Jew of the Week: Raphael Mechoulam

“Godfather of THC”

Raphael Mechoulam

Raphael Mechoulam (b. 1930) was born in Bulgaria to a wealthy Sephardic-Jewish family. The family was forced to flee the country due to rampant anti-Semitism, ultimately surviving the Holocaust and settling in Israel in 1949. During his IDF service, Mechoulam worked as a chemical engineer and helped to develop insecticides. Falling in love with scientific research, he continued to study chemistry after his military service, earned his Master’s from the Hebrew University, then his PhD from the Weizmann Institute. After studies at the Rockefeller Institute in New York, Mechoulam returned to Israel to teach at both of his former universities. His primary field of research is cannabis. In fact, it was Mechoulam who first discovered, isolated, and synthesized THC, the primary active ingredient in cannabis. He would later discover and synthesize other important cannabinoids (a term he coined). Mechoulam was one of the pioneers of medicinal cannabis, and has said that medicinal cannabis could probably replace “ten to twenty percent of all pharmaceuticals”. More recently, he discovered endocannabinoids—molecules similar to THC that are naturally produced by the body, playing a key role in immunity and in regulating human emotions. All in all, Mechoulam published over 350 scientific papers. In 2016, he received a lifetime achievement award at Harvard’s School of Medicine. He was also the subject of an eye-opening documentary called The Scientist. Now a nonagenarian, Mechoulam continues to do research at his Jerusalem lab.

Jews of the Week: Mathilde and Arthur Krim

A Couple that Transformed the World

Mathilde Krim

Mathilde Galland (1926-2018) was born in Italy to Christian parents of Swiss and Italian heritage. While studying in medical school at the University of Geneva, she met an Israeli and converted to Judaism to marry him. She became passionate about her new faith, and the Zionist dream, working tirelessly to help Israeli fighters (especially the Irgun) acquire weapons and funds. After receiving her PhD in biology in 1953, the young family settled in Israel, and Mathilde became a researcher at the Weizmann Institute. During this time, she made important discoveries about viruses and cancer, and was part of the team that first developed a way to determine the gender of an embryo. Mathilde moved to New York after getting divorced, and joined a research team at Cornell University.

Arthur Krim

During this time, she met Arthur B. Krim (1910-1994), the son of Russian-Jewish immigrants. Krim graduated from Columbia Law School in 1932 at the top of his class, and worked at a law firm until the outbreak of World War II. He served for the War Department doing critical military work, attaining the rank of lieutenant colonel. After the war, Krim launched a film studio start-up, Eagle-Lion Films. When it tanked, he became a manager at United Artists, and was given three years to turn a profit. He did it in six months, and went on to head United Artists for over two decades (producing hit films like Dr. No, which brought James Bond to America, and West Side Story, which won a record 10 Oscars). Krim and his partners made United Artists the largest movie producer in the world by 1967. Krim would later co-found Orion Pictures (Amadeus, Dances with Wolves). All in all, Krim was a film studio exec for 46 years – possibly the longest in Hollywood history – produced and distributed over 1000 films, and was called “the smartest man ever to work in the movie industry.” Aside from movies, Krim was an important member of the Democratic Party, and served as its finance chairman. He was a personal advisor to three presidents: Kennedy, Johnson, and Carter.

Mathilde and Arthur Krim were famous for their extensive philanthropy and the huge role they played in the civil rights movement, as well as in ending apartheid in South Africa and Zimbabwe, and advancing human rights all over the world. Mathilde continued to work as a researcher throughout her life, and ran the interferon lab at Sloan-Kettering Institute for Cancer Research between 1981 and 1985. During this time, she was one of the first to identify the grave dangers of HIV-AIDS, and did important research to understand the pathology of the disease. In 1983, she founded the AIDS Medical Foundation, and then co-founded the American Foundation for AIDS Research. Aside from her own research work, the Krims donated millions of dollars to the cause. In addition to 16 honourary doctorates, she was awarded the Presidential Medal of Freedom in 2000, the highest civilian honour in America. Her husband had previously received the Presidential Medal of Freedom in 1969.

Jew of the Week: Ada Yonath

The Woman Who Revolutionized Biochemistry

Ada Yonath (b. 1939) was born in Jerusalem, the daughter of Polish Zionists that immigrated to Israel in 1933. Growing up in poverty, she found solace in books, and was inspired by the Polish-French scientist Marie Curie. Yonath studied chemistry at Jerusalem’s Hebrew University and earned a Ph.D from the Weizmann Institute in 1968. Her focus was on x-ray crystallography, a technique for visualizing biochemical structures. After postdoc studies at Carnegie Mellon and MIT, Yonath returned to Israel to establish the country’s only protein crystallography lab. In the 1980s, she started developing a new crystallography technique that was initially met with a lot of resistance from the scientific community. Yonath silenced her critics with amazing results, and discovered some of the key mechanisms in the body’s production of proteins. By 2001, she unraveled the mysteries of the ribosome, the structure responsible for producing protein from the body’s genetic code. In addition to this, she discovered how dozens of antibiotics impact the ribosome, contributing tremendously to our understanding of antibiotics and drug resistance. The technique she invented, cryo bio-crystallography, is now standard in top biochemistry labs around the world. In 2009, Yonath was awarded the Nobel Prize in Chemistry. That made her the first Israeli woman to win a Nobel Prize, the first Middle Eastern woman to win a Nobel Prize in science, and the first woman to win the Prize in Chemistry in 45 years (and only the fourth overall). Yonath has won a handful of other awards, including the Harvey Prize, the Rothschild Prize, the Wolf Prize, the Albert Einstein World Award of Science, and the L’Oréal-UNESCO Award for Women in Science. Despite being in her 70s, Yonath is still doing very important research in her lab at the Weizmann Institute. Some say she may even be up for a second Nobel Prize! She also hopes to write a novel as soon as she has some extra time. (Click here to see an incredible video of a ribosome working in the body, based on Dr. Yonath’s research.)
