Peter Hauk grew up in Rippberg in the Odenwald, where he passed his Abitur (state school exams) in 1980 at the Karl-Ernst-Gymnasium in Amorbach.
After military service with the Panzergrenadier (armoured infantry) in Münster and Walldürn, he studied forestry at the University of Freiburg and obtained the degree Diplom-Forstwirt.
After an internship at the State Forestry Administration in Gundelsheim, Stuttgart and Künzelsau, he passed the Civil Service Exams.
As Guenther Oettinger retired as chairman of the CDU group in the State Parliament to become Minister-President, Hauk competed - as Oettinger’s preferred candidate - to be his successor; he was defeated in the vote by Stefan Mappus and instead became chairman of the CDU's group in the Baden-Wuerttemberg State Parliament.
In May 2016, Hauk was appointed State Minister for Rural Areas (including agriculture) and Consumer Protection in the government of Minister-President Winfried Kretschmann of Baden-Württemberg.
