Thomas Geraghty, a native of Indiana, embarked on a journey to New York City after completing his education, where he secured a position as a reporter for the esteemed New York Herald and later the New York Tribune. Subsequently, he ventured into the film industry as a publicist, and his talents soon led to a role as a writer for the one-reel comedies of the renowned Sidney Drew. Upon relocating to Los Angeles, Geraghty secured a position as a writer for the illustrious Douglas Fairbanks, and later, he was dispatched to New York by Famous Players-Lasky when the company opened a studio in that city.
During his tenure, he successfully managed the studio for several years before being reassigned to London to oversee the studio's operations in that metropolis. Following his stint in London, Geraghty returned to the United States in 1922. Throughout the 1920s and 1930s, he penned screenplays for various studios, including the highly acclaimed Wings of the Morning, which premiered in 1937.
