...when he was 30, Linus Pauling knew he was the world's best chemist. Ten years later his peers agreed. By then, The Nature of the Chemical Bond (1939) was already on its way to becoming the most influential chemistry book of the century. His biggest biological success came from his 1951 proposal of the alpha-helical fold for protein molecules, which everybody else thought were too large and complex to study. His findings were quickly verified, and Linus' confidence was never higher...

...Belgian-born chemist-entrepreneur, Baekeland had a knack for spotting profitable opportunities. He scored his first success in the 1890s with his invention of Velox, an improved photographic paper that freed photographers from having to use sunlight for developing images. With Velox, they could rely on artificial light, which at the time usually meant gaslight but soon came to mean electric. It was a far more dependable and convenient way to work. In 1899 George Eastman, whose cameras and developing services would make photography a household activity, bought full rights to Velox for the then astonishing sum of $1 million...

Others nearly beat him to it. As early as 1872, German chemist Adolf von Baeyer was investigating the recalcitrant residue that gathered in the bottom of glassware that had been host to reactions between phenol (a turpentine-like solvent distilled from coal tar, which the gas-lighting industry produced in bulk) and formaldehyde (an embalming fluid distilled from wood alcohol). Von Baeyer set his sights on new synthetic dyes, however, not insulators. To him, the ugly, insoluble gunk in his glassware was a sign of a dead...

...specimen of Fleming's mold made its way into the hands of a team of scientists at Oxford University led by Howard Florey, an Australian-born physiologist. This team had technical talent, especially in a chemist named Ernst Boris Chain, who had fled Nazi Germany. Armed with funding from the Rockefeller Foundation, these scientists made it their objective to identify and isolate substances from molds that could kill bacteria. The mission was inspired by the earlier work of Gerhard Domagk, who in 1935 showed that the injection of a simple compound, Prontosil, cured systemic streptococcal infections. This breakthrough demonstrated that...

DIED. SIDNEY GOTTLIEB, 80, eccentric chemist who ran some of the CIA's most shadowy operations, including the agency's infamous mind-control experiments of the 1950s and '60s; in Washington, Va. Gottlieb once said the paucity of U.S. knowledge on the effect of drugs "posed a threat of the magnitude of national survival" to explain the existence of MK-Ultra, a program that mandated dosing unsuspecting citizens with...
