Lough Memorials was founded in 1874 by Uriah Alexander Washington Lough. In 1912 the business re-located to 121 South Market Street. Before retiring U.A. Lough brought his son Charles into the business. Charles eventually retired and sold the business to two of his dedicated employees; Wilson Waltz and Frank Griffin. In 1982 Wilson Waltz sold the business to Merkle Monuments an established family owned memorial business with a tradition of excellence in quality and craftsmanship. Geoffrey Merkle Irwin, grandson of Raymond G. Merkle (founder of Merkle Monuments) is Vice-President in charge of Western Operations.
