Museu de Ecologia Fritz Müller, Museu em Blumenau, Brasil

The Museu Fritz Müller occupies a German-style house built in 1852 in Blumenau's Vorstadt district, where naturalist Fritz Müller lived his final years. Its rooms hold insects, taxidermied animals, fossils, bones, skins, minerals and family belongings, plus a library of over 10,000 ecology titles. The 2008 rains exposed the building's pillars before its June 2012 reopening.

The building dates from 1852 and was Fritz Müller's home in his final years. In 1936 mayor Alberto Stein opened it as the Casa de Fritz Müller, following a proposal by José Ferreira da Silva in the city council. In 1996 the municipal environment foundation took over and renamed it Museu de Ecologia Fritz Müller. After closure in 2008 due to heavy rain, it reopened in June 2012.

The museum bears the name of Fritz Müller, a German naturalist who dedicated himself to studying the local plants and animals. Visitors can see in the rooms and gardens how closely his scientific work connected with the understanding of the Brazilian environment.

The museum occupies the house where Fritz Müller spent his final years, in the Vorstadt neighbourhood of Blumenau. The building was closed in 2008 after heavy rain exposed its pillars, and it reopened in June 2012 following restoration work. Visits cover the rooms of the former residence and the library; the collection is also used for research.

Fritz Müller's collection is larger than what the museum displays: part of his research and specimens are held in European museums and at the National Museum of the Federal University of Rio de Janeiro. The Blumenau building shows insects, taxidermied animals, fossils, bones, skins and minerals, plus belongings of the biologist and his family.
