Grosse and Sons rounded out 100 years of business in Mason in 1987, celebrating the event with the dedication of a Texas Historical Marker for their business. Grosse studied architecture in Germany, and it was he who designed and contracted the rebuilding of the Seaquist Mansion in 1891 (the Seaquist Mansion is located two blocks north on Broad Street). He also designed the Mason County Jail you saw earlier, as well as several fine Mason County churches and several homes.

The rather simple wooden building on the right, with its stuccoed front, has been the home of Grosse Lumber Company for all its 100 plus years. The hardware section of Grosse's is housed in a building of the same style as the two Zesch buildings, but its exact origins are unknown.
