She studied physics at the
University of Leipzig from 1952-1956. In 1959 she moved to the Technical University for Chemistry Leuna-Merseburg, where she held the position of scientific assistant and assistant to the Vice Rector for Research until 1964. It was in this year that she also received her
doctorate, enabling her to move immediately into a job as a senior assistant. She completed this phase of her work in 1968 with her
habilitation.[4]
Starting in 1969, she became a lecturer and then a professor of physical chemistry at the “
Carl Schorlemmer” Technical University in Leuna-Merseburg. In addition, she was appointed director of the process chemistry section. From 1981 to 1990, she was rector at the university.[4]
With the dismantling of the technical college on 31 March 1993, Rätzsch entered early retirement and continued to live in
Merseburg.[4]
In 1985, she chaired a five-day
UNESCO meeting of 16 experts from 15 countries about "Participation of Women in Various Areas of Higher Education" held in
Wroclaw, Poland, in December.[2]
