Robert Pirosh embarked on a remarkable Hollywood career, commencing in 1934 when he was signed by MGM, alongside fellow newcomer George Seaton, as a contributing writer. This marked the beginning of a long and illustrious journey, replete with numerous accolades and accomplishments.
Notably, Pirosh's most distinguished achievement was winning the Academy Award for his screenplay of Battleground (1949),a film based on the pivotal Second World War Battle of the Bulge. This remarkable feat was made all the more impressive by the fact that Pirosh had himself fought as a Master Sergeant with the 35th Infantry Division during the conflict.
Throughout his career, Pirosh demonstrated an impressive range, effortlessly transitioning between dramatic subjects, such as the Oscar-nominated war picture Go for Broke! (1951) and the adventure Valley of the Kings (1954),both of which he also directed. Additionally, he proved himself adept at crafting madcap comedy, as evidenced by his contribution to the classic Marx Brothers farce A Day at the Races (1937).
Some of Groucho Marx's most iconic and hilarious lines are attributed to Pirosh, who also developed a lifelong friendship with the comedian. Following the late 1950s, Pirosh turned his attention to writing television scripts, including the pilot episodes for Laramie (1959) and Combat! (1962).
As his career drew to a close, Pirosh transitioned to teaching, sharing his expertise and insights with the next generation of writers at the University of Southern California.
