Trivia: Commenting on his notorious on-set irascibility in 1977, Jack Klugman replied that he was merely "taking Peter Falk lessons from Robert Blake," invoking the names of two other allegedly hard-to-please TV stars. Klugman grew up in Philadelphia, and after taking in a 1939 performance by New York's Group Theatre, Klugman decided that an actor's life was right up his alley. He majored in drama at Carnegie Tech and studied acting at the American Theatre Wing before making his (non-salaried) 1949 stage-debut at the Equity Library Theater. While sharing a New York flat with fellow hopeful Charles Bronson, Klugman took several "grub" jobs to survive, at one point selling his blood for $85 a pint. During television's so-called Golden Age, Klugman appeared in as many as 400 TV shows. He made his film debut in 1956, and three years later co-starred with Ethel Merman in the original Broadway production of Gypsy. In 1964, Klugman won the first of his Emmy awards for his performance in "Blacklist," an episode of the TV series The Defenders; that same year, he starred in his first sitcom, the 13-week wonder Harris Against the World. Far more successful was his next TV series, The Odd Couple, which ran from 1970 through 1974; Klugman won two Emmies for his portrayal of incorrigible slob Oscar Madison (he'd previously essayed the role when he replaced Walter Matthau in the original Broadway production of the Neil Simon play). It was during Odd Couple's run that the network "suits" got their first real taste of Klugman's savage indignation, when he and co-star Tony Randall threatened to boycott the show unless the idiotic laughtrack was removed (Klugman and Randall won that round; from 1971 onward, Odd Couple was filmed before a live audience). It was but a foretaste of things to come during Klugman's six-year (1977-83) reign as star of Quincy, M.E.. Popular though Klugman was in the role of the crusading, speechifying LA County Coroner's Office medical examiner R. Quincy, he hardly endeared himself to the producers when he vented his anger against their creative decisions in the pages of TV Guide. Nor was he warmly regarded by the Writer's Guild when he complained about the paucity of high-quality scripts (he wrote several Quincy episodes himself, with mixed results). After Quincy's cancellation, Klugman starred in the Broadway play I'm Not Rappaport and co-starred with John Stamos in the 1986 sitcom You Again?. The future of Klugman's career -- and his future, period -- was sorely threatened when he underwent throat surgery in 1989. He'd been diagnosed with cancer of the larynx as early as 1974, but at that time was able to continue working after a small growth was removed. For several years after the 1989 operation, Klugman was unable to speak, though he soon regained this ability. He continued working through 2011, and died the following year at age 90.

Trivia: Though frequently cast in Jewish roles, actor Michael Constantine was actually of Greek extraction. The son of a steel worker, Constantine studied acting with such prominent mentors as Howard DaSilva. The prematurely balding Constantine was playing character roles on and off Broadway in his mid-twenties (he was the Darrow counterpart in the original production of Compulsion), supplementing his income as a night watchman and shooting-gallery barker. In 1959, slightly weary of being ignored by callous Broadway producers and casting directors, Constantine appeared in his first film, The Last Mile (1959), thereby launching a cinematic career that has endured into the mid-1990s. Michael Constantine is perhaps best known for his extensive TV work, notably his four-season (1969-1974) stint as long-suffering high school principal Seymour Kaufman on Room 222 and his starring appearance as night-court magistrate Matthew J. Sirota on the brief 1976 sitcom Sirota's Court.

Trivia: The career of William Prince dates back to his first stage work in the late '30s. On film, Prince came across as handsome and personable, but somehow, despite the fact that he appeared in numerous feature films, his career never caught fire and major movie stardom eluded him. His best movie role was as the good-looking but vapid Christian in the 1950 Cyrano de Bergerac. Ageing gracefully into a solid character actor, Prince remained in demand for film and TV roles into the 1990s. William Prince's latter-day TV reputation rested on his hundreds of soap opera appearances: He played Ken Baxter on Another World, Ben Travis on The Edge of Night, Judge Henderson on Search for Tomorrow, Russell Barry on A World Apart, and the father of the title character in Young Dr. Malone. Prince passed away at age 83 in Tarrytown, NY.

Trivia: Sad-faced American leading lady Dimitra Arliss was prominently featured in several New York and Broadway stage productions of the 1960s and 1970s. Among her stage credits was Arthur Kopit's Indians, in which she played a Native American with an Italian accent. She has been seen in numerous TV character roles, notably Marie Falconetti in the 1976 miniseries Rich Man, Poor Man. Dimitra Arliss' most famous film role was as the amorous "hit lady" in The Sting (1973).

Trivia: American actor Steve Tracy appeared in a few films of the '80s and on television. He is best remembered for playing the recurring role of Percival Dalton on the family series Little House on the Prairie (1974-1983).

Trivia: Many remember Steven Mond as Robbie, the friend of Arnold on the sitcom Diff'rent Strokes who infamously pressures him to use drugs. Mond was a seasoned pro when he started on the series, having already cut his teeth on shows like CHiPs and Quincy, M.E., and he would stay with Diff'rent Strokes until 1985. He then retired from show business, and eventually became a lawyer.

Trivia: A popular Broadway actor who was blacklisted following his refusal to answer questions at the HUAC hearings, actor and World War II veteran Alan Manson rebuilt his career following the McCarthy witch hunts, though he is best remembered for his stage roles in such Broadway hits as Funny Girl and Neil Simon's Broadway Bound. A Brooklyn, NY, native, Manson made his stage debut at 16 before hitting the bright lights of Broadway with his performance in Journey to Jerusalem at 21. Joining a touring wartime acting troupe during World War II, Manson and company attempted to keep morale high in such productions as Three Men and a Horse and Brother Rat. After being noticed by famed composer Irving Berlin, Manson made his film debut in the 1943 feature This Is the Army. Returning to the United States shortly following the end of the war, the now-established actor returned to the Broadway stage with roles in Call Me Mister and Rodgers & Hammerstein's Allegro. Summoned before the HUAC shortly before he was to take the lead in 1955's Blithe Spirit, the actor paid for his silence when he was blacklisted from television until the early '60s. Returning to the stage and screen in the early '70s following a few turbulent years, Manson would continue to make a name for himself with roles in made-for-television movies (Switch [1975] and Charles and Diana: Unhappily Ever After [1992]), theatrical feature films (Bang the Drum Slowly [1973], The Doors [1991]), and such notable television series as Three's Company, The Rockford Files, and Kojak. In March of 2002, Alan Manson died of natural causes in New York. He was 83.
