David Leonard Landau was born on June 22, 1947, in Brooklyn, New York, the youngest son of two Jewish schoolteacher parents, Stella (Goldman) and Saul Landau.^[1]

Lander decided to become an actor when he was 10. He studied at the High School for the Performing Arts and continued at Carnegie Tech and New York University.^[2] It was in high school he took the stage name of David Lander, which he would later legally adopt, after a classmate "borrowed" his real name to register with an actors' union.^[1]

He was best known for his role as Andrew Helmut "Squiggy" Squiggman on the situation comedy Laverne & Shirley from 1976 to 1982 along with sitcom sidekick Lenny, played by Michael McKean.^[1]

Lander's partnership with McKean began during their acting classes at Pittsburgh's Carnegie Mellon University, where they developed the characters of Lenny and Squiggy. After Pittsburgh, they teamed up in the Los Angeles–based comedy ensemble The Credibility Gap. The duo released an album as Lenny and the Squigtones in 1979 featuring Christopher Guest on guitar, credited as Nigel Tufnel, a name Guest would later reuse in the spoof rock band Spinal Tap. Lander and McKean also appeared together in the 1979 Steven Spielberg comedy 1941, and the 1980 Kurt Russell film Used Cars. They also lent their vocal talents to the children's animated TV series Oswald, which ran from 2001 to 2003.

He also played "Tanning Intruder" in Christmas with the Kranks. Lander created the starring role of the demented fast-food franchise clown Bruce Burger in the cult film Funland, directed by Michael A. Simpson.
