The construction of the Jefferson Memorial on the Tidal Basin in Washington, DC, was authorized by Congress in 1934. In 1939, US President Franklin Roosevelt presided over a ceremony during which the cornerstone of the monument was laid. Completed and dedicated in 1943, the white marble building, designed by John Russell Pope, is a circular structure with a domed ceiling, surrounded by 26 columns. Inside is a bronze statue of Jefferson. Why was a temporary plaster statue initially erected there? Discuss
