Albert Pieter Hahn (17 March 1877 – 3 August 1918) was a Dutch political cartoonist, caricaturist, poster artist and book cover designer; well known for his socialist and antimilitaristic viewpoints.

That same year, thanks to a government grant, he enrolled at the "Teekenschool voor Kunstambachten" in Amsterdam and, after graduating, became a drawing teacher at a technical school.

[2] The following year, Het Volk, a socialist newspaper, held a contest to find an artist for their weekly Sunday supplement.

[2] Soon, he began creating political cartoons in addition to illustrations; for De Notenkraker as well as Het Volk, and was able to quit his teaching job in 1905.

Although he had occasional serious relapses, in 1911 he married the recently divorced Iemkje Dijkman, adopted her two sons, and had two daughters.
