Kirchgässner studied 1951-1956 mathematics and physics at the Albert-Ludwigs-University of Freiburg , has been in mathematics at there in 1959 Henry Gortler doctorate and habilitated in 1966. He was then a professor at the University of Bochum and in 1972 at the University of Stuttgart , where he headed the chair for applied mathematics and retired in 1998. Even afterwards he remained scientifically active.

He dealt with dynamic systems, bifurcation theory and hydrodynamic stability, for example with the theory of water waves. He is known for the method of reduction to the spatial center manifold reduction.

He was a member of the Heidelberg Academy of Sciences (1996), corresponding member of the Mainz Academy of Sciences and honorary member of the International Society for the Interaction of Mechanics and Mathematics (ISIMM) and the Society for Applied Mathematics and Mechanics (GAMM), of which he was President in 1980 until 1983 was. Until 2001 he was President of the Society for Mathematical Research Oberwolfach. From 1987 to 1993 he was a member of the Senate of the German Research Foundation. In 1993 he received the Max Planck Research Award .
