Jan Šimsa is a representative of the Christian-oriented dissent of Brno.

As a parish priest of the Evangelical Church of the Czech Brethren, he worked until the forced prohibition of pursuing a profession in 1973.

In the following years, he changed his profession, worked as an archivist, a handyman of church buildings, and after moving to Brno in 1975 as a manual labourer. Šimsa was a signatory of Charter 77 and in 1978, he was arrested and spent eight months in a jail. During normalization, he participated in the organization’s underground university´s lectures, publishing samizdat and leading informal ecumenical dialogs. After the Velvet Revolution he also worked on publishing Božena Komárková's writings after her death, which he kept with his wife Milena Šimsová on her estate, which was donated to the Moravian Museum in 2012. In 1991 Šimsa received the Order of T. G. Masaryk. He died 5. 4. 2016 in Brno.
