Mr. and Mrs. Otto Schumann of 1932 Northeast Thirteenth avenue will celebrate their golden wedding anniversary today. A large number of friends have been invited to help make the day more golden. The executive committee of the Lang Syne society, of which Mr. Schumann has long been a member, sent a letter of congratulation to the happy "young" couple.
Mr. and Schumann and Miss Agnes Giboni were married April 9, 1884, by Justice of the Peace Buschweiler at the northeast corner of First and Washington streets. On October 1 of that year the bride groom started the Otto Schumann Marble & Granite Works, which he operated until a few years ago, when the management was given to his son Otto.
Mr. Schumann was born in Wefensleben, Germany, in 1855, and attended school in Zeitz until he was 14, when he began learning the stonecutter's trade. He worked in Berlin, Hamburg, Bremen and on the great cathedral at Cologne before coming to the United States in 1882. He arrived in Portland October 7, 1883, and has made his home here ever since. His grandparents on his mother's side celebrated their golden wedding 66 years ago, and at that celebration young Otto spoke a long piece of poetry. He will speak that same poem to the guests at his home today.
