A university city from 1477 until 1816, Mainz regained this status with the establishment in 1946 of Johannes Gutenberg University, with which special institutes are associated, including the Institute for Economic Research. 

Also in the city are the Max Planck Institutes for Chemistry and for Polymer Research and the Academy of Sciences and Literature.
