[3] Jacob Burkhardt died on January 16, 1893, and by 1895 Abraham had left school to work for a law firm, studying at night to qualify for the bar.

[8] The publishing venture failed, and Burkhardt's New York career began to wane; in 1923 he was recruited by Fox films and moved to California.

[15] Now based in New York, he wrote lyrics and sketches for revues that included The Mimic World (1908 and 1909) and Florenz Ziegfeld's Miss Innocence (1908).

[18] Both these shows, and many other of Burkhardt's scripts and vaudeville routines, incorporated comic Jewish characters, depicted by stereotypical performers like Alexander Carr and Samuel Liebert.

A final Chicago show, One Girl in a Million (1914) was also a success but effectively marked the end of Burkhardt's musical comedy career.

His publishing firm failed in less than a year, and a review of his 1918 sketch, “Work or Fight,” concluded that “the turn in its present form looks hopeless.”[24] With tastes changing, Burkhart, like many other entertainers, moved west.

He worked on silent films for Fox for several years, culminating in the scenarios for eight short comedies directed by Harold Lloyd and starring Edward Everett Horton.

[25] Then he moved into talkies, writing the scripts for two early Warner Brothers Vitaphone features, The Home Towners and Queen of the Night Clubs.
