In 1959, Heck appeared on
Peter Frankenfelds talent show
Toi – Toi – Toi, singing
Hippe-di-hipp, mein Mädchen. In 1961, he participated in the preliminary round of the Grand Prix Eurovision de la Chanson (now
Eurovision Song Contest). After employment as a car salesman, Heck worked for a record company. He visited the radio station
Südwestfunk (SWF) in Baden-Baden on 23 November 1963 and was asked to be interviewed because a scheduled guest did not show up. The moderator asked clumsy questions so Heck took over conducting the interview himself. As a result, Herbert Falk offered him the job of hosting a 90-minute "Sendung" (broadcast) every Saturday. Heck then worked for
Radio Luxemburg from 1965 to September 1966. It was customary there to use only a first name, and as "Dieter" was already taken, Heck asked readers of the youth magazine
Bravo for an alternative name. The readers chose "Thomas", and he used it since. He collaborated with
Frank Elstner and they became friends. He then worked for
SR 1 Europawelle of the
Saarländischer Rundfunk. He concentrated on German
Schlager music, a topic not favored by other moderators. His series
Die Deutsche Schlagerparade was so successful that it was partly recorded. In 1967, he was a co-founder of the award
Goldene Europa for German singers, which was first awarded in 1968. Heck's breakthrough came with
ZDF-Hitparade, a TV series for the
ZDF in
Mainz, based on the model of the Schlagerparade and staged by Truck Branss. It was considered an influential music feature of the 1970s and 1980s. He presented it 183 times between 1969 and 1984. He showcased international performers, but they had to sing in German, including the Lebanese
Ricky Shayne, the Greek
Costa Cordalis, ,
Mireille Mathieu,
Mouth & McNeal,
Karel Gott,
Michael Holm and
Marianne Rosenberg. Heck initiated the award
Goldene Stimmgabel. From 1982 to 1989, he was also moderator for the Südwestfunk in the series
Gute Laune aus Südwest and
Vom Telefon zum Mikrofon. For the ZDF, he moderated
4 gegen 4 (1973),
Die Pyramide (1978),
Schwarz auf Weiß,
Ihr Einsatz bitte – Made in Germany,
Das ist ihr Leben (1994),
Das große Los,
Showpalast,
Das Sommer-Hitfestival,
Das Silvester-Hitfestival and finally
Melodien für Millionen (Melodies for Millions), a gala for the benefit of the
German Cancer Aid. He retired from the ZDF in 2007. He said then "It was my life to entertain people. That I succeeded makes me happy."("Mein Leben war es, Menschen zu unterhalten. Dass mir dies gelungen ist, macht mich glücklich"). Heck published his biography in 2011. As an actor, in 1970 he starred in the role of the presenter in the TV play
Das Millionenspiel. He played supporting roles in TV crime series, such as
Tatort in 1981,
Rosenheim-Cops,
Praxis Bülowbogen, and
Stuttgart Homicide in 2009. == Personal life ==
