Hans Geiger (1882)

Fri, 30 Sep 2016 05:00:00 GMT

(image) After receiving a doctorate in physics in Germany in 1906, Geiger traveled to England, where he assisted chemist Ernest Rutherford. In 1908, they designed an instrument to detect and count alpha particles, positively charged ionizing particles produced by radioactive decay. He then returned to Germany, directing radiation research at several universities. Two decades later, Geiger developed the sensitive, portable radiation counter that now bears his name. Geiger was a member of what "club"? Discuss



László Bíró (1899)

(image) Frustrated by the way his fountain pen's sharp tip would tear paper and by the amount of time he wasted filling the pen with ink and cleaning up smudges, László Bíró set to work developing a better pen. A Hungarian newspaper editor, he noticed that the ink used in newspaper printing dried quickly and without smudging, but it was too viscous for use with existing pens. With the help of his brother, a chemist, he developed the modern ballpoint pen. How long did it take him to build his pen?



Ed Sullivan (1901)

(image) Famed American TV host Ed Sullivan started out as a journalist and gossip columnist but was hired by CBS to host the variety program that eventually became The Ed Sullivan Show because of his talent for discovering interesting performers. The program, featuring diverse entertainment, became a national institution for over 20 years, while Sullivan's terse introductions of guests and distinctive mannerisms made him a popular target for comedians. What acts were banned from Sullivan's show?
