Allison-Antrim Museum’s “virtual” November speaker is local historian, Tim Rockwell, Mercersburg, introduced by the late Ted Alexander.

Rockwell spoke 16 years ago in April 2004 about Sgt. Patrick Gass’ Franklin County roots and his important role in the Lewis and Clark Expedition.  2004 marked the middle of the 200th Anniversary Commemoration of the Lewis and Clark Expedition, 1803 – 1806. Patrick Gass’ home in Chambersburg is part of the Franklin Farms complex.

While Lewis and Clark and their legendary Indian guide, Sacajawea, are well known, many have never heard of Gass. As chief carpenter for the expedition, Gass built the winter quarters, wagons, and dugout canoes, among many other accomplishments while on the trek.

Rockwell is the former Dean of Students at the Mercersburg Academy and is an historical archeologist who has done work for The Smithsonian Institution, The National Park Service, and The National Trust for Historic Preservation.
