Carl Djerassi, an eminent chemist who 63 years ago synthesized a hormone that changed the world by creating the key ingredient for the oral contraceptive known as “the pill,” died at his home in San Francisco on Friday last week. He was 91.
His son, Dale, said the cause was complications of liver and bone cancer.
Djerassi arrived in the US as World War II engulfed Europe, a 16-year-old Austrian Jewish refugee who, with his mother, lost their last US$20 to a swindling New York cabdriver. He wrote to then-US first lady Eleanor Roosevelt, asking for assistance, and obtained a college scholarship. It was a little help that made a big difference.

Djerassi wrote books, plays and 1,200 scientific articles; taught at universities for five decades; created an artists’ colony in California; and obtained a patent on the first antihistamine.
His work on the science of birth control helped engender enormous controversies and social changes, altering sexual and reproductive practices, family economics and the working lives of millions of women around the world.
While never a household name, Djerassi was often called the father of the pill. However, it was something of an exaggeration. He did not invent the commercial birth-control pill, and was only one of many scientists working over decades who pioneered the chemical bases of what would become the pill.
And even on the day of the breakthrough, he was one of two chemists working with a student assistant at a small pharmaceutical laboratory in Mexico City who first synthesized a progestin called norethindrone, which became the key ingredient of the pill. It was on Oct. 15, 1951 — one of those dates recorded for posterity — a year before others created similar compounds in other labs.
Scientists had long known that high levels of estrogen and progesterone inhibited ovulation, but synthesizing them from animal or plant extracts had proved expensive and ineffective for use as oral contraceptives.
The synthesis by Djerassi and his colleagues, George Rosenkranz and the student, Luis Miramontes, was both economical and effective for oral use. All three names went on the patent.
At first, the team deemed it a breakthrough for fertility, not birth control. While its significance as a pregnancy inhibitor was soon recognized, five years of trials were needed to demonstrate its relative safety and effectiveness. Even then, drug companies were reluctant to market the pill, fearing boycotts of their products by religious groups and others opposed to birth control.
In the 1960s, however, the pill — based also on pioneering work by M.C. Chang, Gregory Pincus, John Rock and others, and technically known as the combined oral contraceptive pill — was developed and marketed by various drug companies.
Use of the pill spread rapidly, producing vast economic and social effects. It gave women unprecedented control over fertility, separating sex from procreation. It let couples plan pregnancies and regulate family size, and women plan educations and careers. It also generated debates over promiscuity and the morality of birth control. The Roman Catholic Church, in particular, emphasized its bans on artificial contraception.
The pill made Djerassi wealthy and something of a celebrity as he moved through a series of careers as a professor of chemistry, an insect-control entrepreneur, an art collector, a rancher, an author of science novels and nonfiction books as well as a poet, playwright and founder of an artists’ colony.
“Yes, I am proud to be called the father of the pill,” he told Nicholas Wroe of the Guardian newspaper in 2000. “But identifying scientists is really only a surrogate for identifying the inventions or discoveries. Maybe it is true that Shakespeare’s plays would never have been written if it wasn’t for Shakespeare. But I’m certain that if we didn’t do our work, then someone else would have come along shortly afterwards and done it.”
Djerassi was born in Vienna on Oct. 29, 1923, to Samuel and Alice Friedmann Djerassi. His parents were physicians who divorced when he was six.
In 1938, when Nazi Germany annexed Austria and 70,000 Austrian Jews and communists were quickly rounded up, the elder Djerassi returned to Vienna and remarried his wife in order to take her and Carl out of the country. The marriage was soon annulled, and Carl and his mother made their way to the US in 1939, settling in upstate New York, where his mother worked in a group medical practice. His father emigrated to the US in 1949.
With a scholarship arranged through Roosevelt’s intercession, Carl briefly attended Tarkio College in Missouri, then earned a bachelor’s degree with honors in chemistry at Kenyon College in Ohio in 1942, when he was not quite 19. In 1945, he earned a doctorate at the University of Wisconsin and became a naturalized US citizen.
Married three times, Djerassi is survived by his son, a grandson and a stepdaughter.
Chinese President Xi Jinping (習近平) is to visit Russia next month for a summit of the BRICS bloc of developing economies, Chinese Minister of Foreign Affairs Wang Yi (王毅) said on Thursday, a move that comes as Moscow and Beijing seek to counter the West’s global influence. Xi’s visit to Russia would be his second since the Kremlin sent troops into Ukraine in February 2022. China claims to take a neutral position in the conflict, but it has backed the Kremlin’s contentions that Russia’s action was provoked by the West, and it continues to supply key components needed by Moscow for
Japan scrambled fighter jets after Russian aircraft flew around the archipelago for the first time in five years, Tokyo said yesterday. From Thursday morning to afternoon, the Russian Tu-142 aircraft flew from the sea between Japan and South Korea toward the southern Okinawa region, the Japanese Ministry of Defense said in a statement. They then traveled north over the Pacific Ocean and finished their journey off the northern island of Hokkaido, it added. The planes did not enter Japanese airspace, but flew over an area subject to a territorial dispute between Japan and Russia, a ministry official said. “In response, we mobilized Air Self-Defense
CRITICISM: ‘One has to choose the lesser of two evils,’ Pope Francis said, as he criticized Trump’s anti-immigrant policies and Harris’ pro-choice position Pope Francis on Friday accused both former US president Donald Trump and US Vice President Kamala Harris of being “against life” as he returned to Rome from a 12-day tour of the Asia-Pacific region. The 87-year-old pontiff’s comments on the US presidential hopefuls came as he defied health concerns to connect with believers from the jungle of Papua New Guinea to the skyscrapers of Singapore. It was Francis’ longest trip in duration and distance since becoming head of the world’s nearly 1.4 billion Roman Catholics more than 11 years ago. Despite the marathon visit, he held a long and spirited
China would train thousands of foreign law enforcement officers to see the world order “develop in a more fair, reasonable and efficient direction,” its minister for public security has said. “We will [also] send police consultants to countries in need to conduct training to help them quickly and effectively improve their law enforcement capabilities,” Chinese Minister of Public Security Wang Xiaohong (王小洪) told an annual global security forum. Wang made the announcement in the eastern city of Lianyungang on Monday in front of law enforcement representatives from 122 countries, regions and international organizations such as Interpol. The forum is part of ongoing
