While attending East 15 Acting School, Martin von Haselberg and Brian Routh invented a character they called Harry Kipper. Upon being expelled from the school on the claim of "too experimental", they began working as a touring act. They were originally called Harry and Alf Kipper and had two distinctly different characters. Later, they dropped the name Alf and decided to call each other Harry and make their characters identical.^[1]

From 1971 to 1975, most of their performances took place in Europe.^[1] In 1974, David Ross, later director of the Whitney Museum of Art and the San Francisco Museum of Modern Art, saw them in performance at Gallerie Rudolf Zwirner in Cologne and invited them to do some shows in California.^[2] The Kipper Kids moved to Los Angeles in 1975 and became associated with the early years of punk.^[3]

In 1982, they stopped actively collaborating. Their final performance together was at the National Review of Live Art, Glasgow, in 2003. ^{[citation needed]} They reunited as The Kipper Kids in 2018 to perform the song "Mah Nà Mah Nà" for the album Dr. Demento: Covered in Punk.

Quoting from an announcement for the Berkeley Art Museum: "Through actions that at times stress the visual, and the violent aspects of social rituals, the British Team of Harry and Harry Kipper perform in a fashion that combines the zany theatrics of Spike Milligan with a scatological slapstick that is all their own". Routh and von Haselberg created elaborate but purposely low-tech installations in which they would perform "ceremonies" using mostly found objects. Examples are "Tea Ceremony" (1972) a Japanese tea ceremony-inspired piece and "Boxing Ceremony" (1972) in which one performer beats himself until bloodied whilst the other acts as referee. Japanese rituals, English music hall, Viennese Actionism, and the work of Samuel Beckett were amongst their influences.

The Kipper Kids made two projects for television. For HBO they produced Mum's Magic Mulch, and for Cinemax, K.O. Kippers, while the Kids also appeared in a 1982 project for HBO executive-produced by von Haselberg, The Mondo Beyondo Show, a one time presentation for performance artists (including a pre-Stomp Yes/No People, La La La Human Steps, Bill Irwin, Paul Zaloom and others) hosted by Bette Midler's Mondo Beyondo character. Von Haselberg made a number of films at the American Film Institute with Routh in the lead role: Quiet Lives (1991), People Are No Damn Good (1991) and Your Turn To Roll It #54 (1992). They also were seen as characters in the 1982 film Forbidden Zone and the 1989 film UHF. Another television appearance came during the fifth season of ABC's Moonlighting. First aired on Valentine's Day, 1989, "I See England, I See France, I See Maddie's Netherworld" featured The Kipper Kids as a pair of gravediggers in a surreal dream sequence. The Kipper Kids also performed a song in the 1991 comedy film The Addams Family: "Playmates" which can be heard in the film and on its soundtrack.

Later, Martin von Haselberg created a series of large photographic images made into inflatable sculptural shapes titled Floatulents,^[4].

Von Haselberg has been married to Bette Midler since 1984. They have one daughter together, actress Sophie von Haselberg.^[5]
