TODAY IN SCIENCE HISTORY
NEWSLETTER - 27 FEBRUARY

Feature for Today
Constantin FahlbergOn 27 Feb 1879, the artificial sweetener, saccharin, was discovered by Constantin Fahlberg. He had been investigating products from coal tar, and one day, he went to have dinner, leaving the laboratory without washing his hands.

Oh, horror! The bane of every chemistry teacher, who drums it into the heads of every student to always wash your hands before leaving the lab.

But for Fahlberg, this was a serendipitous act of neglect, as you can read in his own words in this article on the Discovery of Saccharine.


Book of the Day
The General: David Sarnoff and the Rise of the Communications Industry On 27 Feb 1891, David Sarnoff was born, American pioneer in broadcasting, spanning from the first national radio network to colour  television. Today's Science Store pick is The General: David Sarnoff and the Rise of the Communications Industry, by Kenneth Bilby, who writes an authoritative biography of a business leader who wielded enormous influence over the course of the 20th century. Sarnoff was the creator of the first national broadcasting network and pioneer of color TV, as was RCA's president at age 39. The book title refers to Sarnoff's rank during World War II when RCA converted to defense production while Sarnoff as a reserve colonel, and later general, headed Allied communications in Europe. In the broadcasting industry, Sarnoff had an autocratic managerial style, and was a fierce rival. Available from $2.95 (as of time of writing).
