Leon C. Weiss

Leon Charles Weiss (December 10, 1882 – April 1, 1953) was a politically connected American architect who designed most major monuments of the Huey Pierce Long, Jr., gubernatorial administration in Louisiana, including the skyscraper-shaped capitol, the governor's mansion, and Louisiana State University buildings, all in Baton Rouge, and the LSU Medical School in New Orleans.

Charity Hospital (New Orleans) was designed in 1939 by the firm of Weiss, Dreyfous, and Seiferth

Weiss was born in Farmerville in Union Parish, north of Ruston. In 1903, he graduated from engineering school at Tulane University in New Orleans He formed the Weiss and Dreyfous firm in New Orleans in 1920 with F. Julius Dreyfous. The name was changed in 1927 to Weiss, Dreyfous, and Seiferth, when Solis Seiferth entered the firm.

In the 1920s, the firm designed the Jung and Pontchartrain hotels in New Orleans and the Eola Hotel in Natchez, Mississippi. They also designed the Granada Theatre in New Orleans, Louisiana. The three partners met Long and financially backed him for governor in 1928 and successfully opposed his impeachment in 1929.

The company continued to design state buildings in the Richard Webster Leche administration (1936–1939). These included Charity Hospital ("Big Charity") in New Orleans and other university structures.

Weiss (not Dreyfous and Seiferth) was indicted in 1939 during the "Louisiana Hayride" scandals for having used the United States mail to defraud in regard to an unspecific building contract for Louisiana Tech University in Ruston in Lincoln Parish in north Louisiana. Critics said that Weiss' trial was marked by "guilt-by-association" tactics used by the U.S. attorney, Malcolm Lafargue, and by anti-Semitism. He was convicted in 1940 and imprisoned. He resumed his practice in 1952, only a year before his death. With Edward Silverstein, he managed to design an addition to the Jung Hotel.

Weiss died in New Orleans.
