Peter Roman Heid completed a "sculptor apprenticeship" (Bildhauerlehre) as a wood and stone sculptor before the war, after which he undertook further training as a ceramist from 1946 to 1948. Then in 1948 he did his sculptural studies at the Academy of Fine Arts in Munich under the tutelage of Josef Henselmann. Since 1950, he has been his master pupil.

Since 1955, Heid has worked as a freelance sculptor and designed many churches and public places in the following decades. More than twenty years he has also rendered outstanding services to the sculptural newcomers. From 1970 to 1992, he was the head of the School of stonemasons and sculptors at the Master School of Kaiserslautern and since 1988, he was announced as their director. Since his retirement in 1992, he has worked exclusively as a freelance sculptor.
