Theo Funke Küpper was a Dutch comic artist, (advertising) illustrator and (watercolor) painter. He was born Theodorus Franciscus Anton Funke Küpper as the middle son of the Westphalian painter Bernard Anton Funke Küpper, who moved to Rotterdam after marrying a Dutch girl. His brothers Albert Funke Küpper and Frans Funke Küpper had also inherited their father's artistic talents. Theo' career evolved similarly to that of his brother Frans. Around 1930, he was employed as an advertising designer by the Rotogravure Maatschappij in Leiden.
He moved over to the ad department of De Spaarnestad in Haarlem in 1934. When the studio closed its doors in 1935, he became a freelance illustrator and comics writer for the Catholic children's magazines Kleuterblaadje and (Weekblaadje voor de) Roomse Jeugd, the forerunners of the magazines Okki and Taptoe.
His gag strip 'De Verstrooide Professor' ('The Confused Professor') ran in Kleuterblaadje and its successor Okki on a weekly base between 1937 and 1966, with an interruption during the war. When Kleuterblaadje became Okki in the mid 1950s, he added another professor and changed the title in 'De Verstrooide Professors'. When Okki moved over from De Spaarnestad to Malmberg in Den Bosch in January 1966, Theo Funke Küpper ended his collaboration. Theo had also written the texts for a weekly column, called 'Jan Jokkebrok', which was illustrated by his brother Frans and published in Weekblaadje voor de Roomse Jeugd from 1937 until the Second World War.
Theo Funke Küpper passed away in Haarlem on 5 July 1977.
