David Joseph Bohm FRS (20 December 1917 – 27 October 1992) was an American quantum physicist who contributed to theoretical physics, philosophy of mind, and neuropsychology. Due to suspicions of Communism during the McCarthy era, he left the US, eventually becoming a British citizen. Bohm is widely considered to be one of the most significant theoretical physicists of the 20th century.

Bohm was born in Wilkes-Barre, Pennsylvania, United States, to a Hungarian Jewish immigrant father and a Lithuanian Jewish mother. He was raised mainly by his father, a furniture store owner and assistant of the local rabbi. Despite being raised in a Jewish family, he later on became an agnostic in his teenage years. Bohm attended Pennsylvania State College (now The Pennsylvania State University), graduating in 1939, then attended the California Institute of Technology for a year, and then transferred to the theoretical physics group directed by Robert Oppenheimer at the University of California, Berkeley, where he eventually obtained his doctorate degree.

"Professor" Irwin Corey (born July 29, 1914) is an American comic, film actor and activist, often billed as "The World's Foremost Authority". He introduced his unscripted, improvisational style of stand-up comedy at the well-known San Francisco club, the hungry i.

Lenny Bruce once described Corey as "one of the most brilliant comedians of all time".

Irwin Corey was born in 1914 in Brooklyn, New York. Poverty-stricken, his parents were forced to place their six children in the Hebrew Orphan Asylum of New York, where Corey remained until the age of 13, when he rode the rails out to California, and enrolled himself at Belmont High School in Los Angeles. During the Great Depression, he worked for the Civilian Conservation Corps, and while working his way back East, became a featherweight Golden Gloves boxing champion.

Corey supported left-wing politics. "When I tried to join the Communist Party, they called me an anarchist." He has appeared in support of Cuban children, Mumia Abu-Jamal, and the American Communist Party, and was blacklisted in the 1950s, the effects of which he says still linger to this day. (Corey never returned to Late Night with David Letterman after his first appearance in 1982, which he claimed was a result of the blacklist still being in effect.) During the 1960 election, Corey campaigned for president on Hugh Hefner's Playboy ticket. Corey was a frequent guest on the "Tonight Show" hosted by Johnny Carson during the late 1960s and early 1970s.
