William Thackara (ca. 1771–1823), plasterer, worked on Philadelphia’s Congress Hall, 1793–95, on both the Bank of Philadelphia and the United States Capitol in 1808, and on the Pennsylvania State House (later known as Independence Hall) in 1816. In 1804 he was a founder and the first president of the Master Plasterers’ Company of Philadelphia. Thackara worked at various times with architects Benjamin Henry Latrobe, Robert Mills, and William Strickland on a number of Philadelphia’s finest buildings. In 1817 he declined the commission for plastering the President’s House in Washington when commissioner Samuel Lane would not agree to the terms used by the Master Plasterers’ Company. Thackara died in Philadelphia (Robert Donald Crompton, “William Thackara, Jr.: Master Plasterer of Early Philadelphia,” Plastering Industries 46 [Oct. 1960]: 27–37; Latrobe, Papers description begins John C.
