The Emergence of 'Professor Lucifer G. Butts'
1915
This period marked the rise in popularity of some of Goldberg's most iconic cartoon series, particularly those featuring Professor Lucifer G. Butts, the prototype for many of his future 'inventor' characters. These cartoons, depicting elaborate and impractical contraptions, cemented his fame and established the 'Rube Goldberg machine' as a cultural phenomenon.
