41 Lumber hosted a customer appreciation day Thursday at its location at 6669 N. U.S. 2/41 and M-35 in Escanaba to celebrate the company’s 100th year. 41 Lumber is a full-service building material supply and project design service company. They were founded in 1925 by Edward A. Hammer and Albert Quandt as Prior Lumber Co., with a single location in Houghton. They have since grown to six retail locations, a distribution center and a design center and employ about 90 people in the Upper Peninsula. They are now led by the third and fourth generations of the Quandt family. From left are David Quandt, Steve Quandt and Carol Quandt. (Submitted photo)
