Wehr Dam figures predominately in the history of Lehigh County, particularly in South Whitehall's history. William Wehr was born in 1871 and worked at H. Leh and Company in Allentown. While there he attended the American Business College in the evenings, graduating in 1894. By 1903 he began working at Sieger Mill, and purchased it in 1905. He remodeled the operation with the most modern rolling equipment, and soon the renamed Wehr Mill was producing his famous White Rose Flour. The concrete mill dam, considered the best constructed in the area, still delights residents of Lehigh Valley, and ties them to our agricultural and milling history.
