Article in Gospel Messenger, A Publication by the Church of the Brethren
(in the top right column, second paragraph down, there is a blurb about Opa coming to McPherson College)
The Gospel Messenger - December 16, 1939
Recently there has come to our camps Thomas Daeppner, a German refugee student. Mr. Daeppner is a sophomore, a non-Aryan, and is supported on our campus by other students and groups from the city of McPherson.
Opa's arrival is mentioned in this little blurb in the Gospel Messenger, a publication by the Church of the Brethren. McPherson College was built by the Church of the Brethren, which is why Opa was asked to promise not to drink, smoke, or dance. ha.
I love how invested the community has been in Opa. They may have spelled his last name wrong and awkwardly called him non-Aryan, but all-in-all, these are really good people.
