Born in Medford, Massachusetts, United States, Baird hosted Professor Quiz from May 9, 1936, until the show concluded July 17, 1948.
He claimed to be an orphan; however, his 1918 draft card recorded him as "living at home in Medford with his folks and attending college".
As it turned out, Baird's disappearance was manufactured so he could avoid paying alimony or child support to his wife.
He later made his way to New York City and masqueraded as "Dr. Craig Earl", scholar and world traveler, taking the job as "quizmaster" on Professor Quiz in 1936.
The identity of "Professor Quiz" was a closely guarded secret until a Radio Daily article revealed him to be "Dr. Craig Earl" in 1937.
