Themmen was born on June 25, 1959, in Boston, Massachusetts, to Ivana Marburger Themmen and Harold B. Themmen, both classical musicians. Themmen's mother was a renowned composer for orchestras in the late 20th century. A guitar concerto of hers was in final contention for the 1982 Kennedy Center Friedheim Award. Themmen's father, a graduate of the New England Conservatory of Music, was a clarinetist and librarian for the American Ballet Theatre, and also played for the Boston Pops Orchestra.
Themmen appeared in radio and TV commercials, voice-overs and theater performing on Broadway in Mame with Ann Miller in 1967 and in The Rothschilds in 1970. In 1971, aged 11, he got his breakthrough role in Willy Wonka and the Chocolate Factory as Mike Teevee.
Declaring a hiatus from acting at age 14 to "just be a kid," Themmen went on to receive a B.F.A. in theatre from New York University. He founded Access International, a travel service that arranged Europe-bound charter flights for backpackers.
