Sherman's Masonic Lodge
This imposing structure is the Travis Masonic Lodge #117, "charted by the Grand Lodge of Texas on February 10, 1852 and set to labor on August 28, 1852".
Their website lists these historical figures as former or present Masons: Solomon-King of Israel, George Washington, Benjamin Franklin, Franklin D. Roosevelt, Harry S. Truman and Buzz Aldrin to name a few. Of course, I'm rather sure they were not members of this particular lodge.
Although this organization has always seemed shrouded in secrecy, their community outreach includes caring for the sick and providing homes for widows and orphans.
