The Gumps was created by Sidney Smith in 1917, launching a 42-year run in newspapers from February 12, 1917, until October 17, 1959.
The Gumps made its debut in an unusual way. Cartoonist Sidney Smith had previously drawn and written Old Doc Yak, a talking-animal strip that sustained only a brief run. The very last Old Doc Yak strip depicted Yak and his family moving out of their house, while wondering who might move into the house next. On Thursday, February 8, 1917, the last panel showed only the empty house. On Monday, February 12, 1917, after the Gumps were introduced in the space formerly occupied by Old Doc Yak, they moved into the house formerly occupied by the Yak family.
