- Fremont Bridge (historylink.org)
The Fremont Bridge, the first double-leaf bascule drawbridge spanning the Lake Washington Ship Canal, opened June 15, 1917, 19 days before the Government Locks at Ballard were officially dedicated. The bridge links the neighborhoods of Fremont and north Queen Anne, previously connected by a streetcar-carrying wooden trestle.
- Otto Hahn (Wikipedia)
Otto Hahn (pronounced [ˈɔtoː ˈhaːn]; 8 March 1879 – 28 July 1968) was a German chemist who was a pioneer in the fields of radioactivity and radiochemistry. He is referred to as the father of nuclear chemistry and discoverer of nuclear fission, the science behind nuclear reactors and nuclear weapons. Hahn and Lise Meitner discovered isotopes of the radioactive elements radium, thorium, protactinium and uranium. He also discovered the phenomena of atomic recoil and nuclear isomerism, and pioneered rubidium–strontium dating. In 1938, Hahn, Meitner and Fritz Strassmann discovered nuclear fission, for which Hahn alone was awarded the 1944 Nobel Prize in Chemistry.
