Claire Rufer-Eckmann (1914-1974) was born in Wabern, Switzerland, and died in Bern. Before receiving her architecture degree in 1937, Rufer-Eckmann traveled to Sweden and Finland, studying under Gunnar Asplund and Alvar Aalto. She returned to Sweden in 1938 and lived there for two years eventually writing an unpublished report on her travels to Sweden and its architecture illustrated with ink drawings of plans and views of important buildings (present in collection).

1942 saw her return to Bern where she began to work with her husband Oskar Rufer, a developer and architect. They remained in practice together for 34 years. Their firm handled a wide variety of projects from shopping centers, theaters, schools, residential, and factories. Rufer-Eckmann specialized in design while her husband concentrated on management and development. Oskar Rufer closed the office upon Claire's death in 1974.

Rufer-Eckmann also participated in SAFFA 58 (The Swiss Exhibition for Women's Work) an exhibition held in Zurich, that focused on "women in the family, occupation and state." These exhibitions were organized and produced entirely by women and the exhibition buildings for SAFFA 58 were designed and built by Swiss women architects.
