W. L. MUELLER.
W. L. Mueller was born February 21, 1867, and is a son of Christian Mueller, of whom extended mention is made elsewhere in this volume. The public schools afforded him his early educational privileges and he afterward attended Griswold College. He then became connected with the lumber business which was founded and conducted by his father, spending the first year on the river and in keeping books. Like his brothers, he passed through every department of the business in order that he might thoroughly acquaint himself with the trade, not only in the management of the financial interests but also in the value of lumber. It was in 1895 that he was admitted to a partnership and since the death of the father the business has been carried on by the sons, W. L. Mueller being now the vice president of the Mueller Lumber Company. He gives his undivided time and attention to the management and development of the business and his efforts have constituted an important factor in its expansion and substantial growth.
In 1893 Mr. Mueller was married to Miss Bernhardine Lennhuis, a native of Davenport and a daughter of Bernhard Lennhuis, one of the old settlers of Scott county. They now have two children, Ben and Annie. Mr. Mueller belongs to the Turners and other societies, in which his social qualities and generous spirit have rendered him popular.
