The collection belonged to Prof. Dr. Rudolf Ewerhart who died in 2022 at the age of 94. Prof. Ewerhart was a musician, a conductor, a musicologist and a collector of musical instruments.

His speciality was Early Music and he was highly influential in the world of ecclesiastical music. In 2020 he received the Papal Order of Gregory in recognition of his life’s work

Prof. Ewerhart lived in Burghaus Wassenach near Lake Laacher, south of Bonn, Germany. Here, in this renovated manor house, he built up possibly the most important private collection of historical musical instruments in Germany. He was known to regularly tour Europe towing a trailer behind his car, in search of more items for his collection.

Following his death, the family decided that his instruments should be sold and find new homes where they can be valued and cared for.
