Miksa Róth (1865-1944) glass strainer and mosaic artist significantly contributed to the beautiful buildings of the University of Debrecen in the first part of the 20^th century. It is regarded that his most famous work here is the five big glass windows in the Hall of the university that were reconstructed in 2012. Furthermore, he left the result of his artistic work in other buildings of the university. Nevertheless, these works were destroyed nearly without exception. The only exception is the three glass windows, which were discovered in the basement of the Surgery Clinic. They were taken out from there in 2018 and the following study introduces the history of the reconstruction.
