Frank Ripploh (September 2, 1949 – June 22, 2002) was a German actor, film director, and author. He is best remembered for his semi-autobiographical 1981 movie Taxi zum Klo. The film, produced on a shoestring budget of 100,000 DM, explored the day-to-day life of a Berlin schoolteacher who also led a very active gay sex life. Extremely explicit, especially for its day, Taxi zum Klo was considered groundbreaking for the subject matter it portrayed, and achieved something of a cult status among gay audiences of the time. Ripploh directed a sequel Taxi Nach Kairo (1987) that was never released in the U.S.
He also participated in the creation of a small number of other art house films during the 1980s, and had a role in the 1982 movie Querelle directed by Rainer Werner Fassbinder. Ripploh died of cancer in 2002.
