Biographie

Witwer was born on March 11, 1890 in Athens, Pennsylvania, and briefly attended Saint Joseph's College in Philadelphia. He worked in odd jobs—errand boy for a butcher, prize fighter manager, and a soda jerk on Broadway—for a time before starting to write for newspapers, counting the St. Cloud (Florida) Tribune and
New York newspapers Brooklyn Eagle, the New York American, the New York Mail, and The Sun as employers.

In 1912, he married Zada "Sadie" Schagrin of Yonkers, New York. His first recorded film contribution at the Internet Movie Database () was writing intertitles for the 1916 silent film Where D'Ye Get That Stuff?. In 1917—during World War I—he was sent to France by Collier's magazine as a war correspondent. He also wrote for McClure's in this time period.

By the early 1920s, Witwer's works were starting to be filmed, with nearly 30 film credits recorded by the by 1925. In May 1925, his income was reportedly more than that of Ring Lardner. Witwer is credited with producing ten shorts beginning in 1925, but he was most active as a writer, receiving writing credits for 30 more short films after 1925.

In the mid-1920s, Witwer collaborated on two newspaper comic strips. In 1924, he began the strip Samson and Delia with Tim Early and Paul Robinson, which ran for two years. In 1925, he created Switchboard Sally with Wesley Morse.

Witwer relocated to California in 1926 to regain his health, which he apparently did, remaining in good health until he fell ill in May 1929.
