'Leon Emile Dessez was born April 12, 1858 in Washington, D.C., one of eleven children of French immigrants Leon Dessez Sr. and Wilhemina Gebhardt, who had German ancestry. Dessez Sr. was a civil engineer, having been trained in Paris, and designed fortifications for the Confederacy during the Civil War. Dessez Jr. remained with the rest of his family in Washington throughout the war and attended the local schools there. At age 19, he began learning architecture at the firm of Hornblower and Poindexter. With no formal university training, he then worked on the design of the Washington Monument under Thomas L. Casey, after which he was an assistant to the architect of the Washington Navy Yard. Dessez was designing houses in the city as early as 1882 and in April 1886, he opened a private architectural practice.

A significant early commission was the home of Henry and Lucinda Cady in the Takoma neighborhood of Washington, which was listed on the National Register of Historic Places in 1975. He designed another smaller house in the area, after which he became involved in the development of Chevy Chase, Maryland. This new Washington suburb was being developed by Francis Newlands, for whom Dessez created building regulations for the community and designed the first two homes as chief architect for the Chevy Chase Land Company, a position he held for almost three decades.

In the early 1890s, he continued to design houses including one for Francis Newland, and the Admiral's House at the Naval Observatory in 1893, which is now the residence of the vice-president of the United States.

Also around that time, he designed the conversion of a office building into the Raleigh Hotel on Pennsylvania Avenue, a very prominent location. After this project, he was involved in the design of many municipal buildings including hospitals, fire stations, and other civic building.

In 1919, Dessez designed the "first 20th century prison without bars" for Washington, located in Occoquan, Virginia. It was designed so that prisoner would receive sunlight and ventilation in their cells. This design was directed by Washington's first municipal architect, Snowden Ashford

He designed the Normal School for Colored Girls which was built in 1913 and listed on the NRHP in 1991. It is now part of the University of the District of Columbia. He may have worked on buildings at the Gallinger Hospital also.

He was an early adopter of reinforced concrete, credited with the first office building in the city made completely of the fireproof material, the design dating to 1899.

Profession

Dessez did not specialize in any building type or architectural style. He did big and small jobs, private, corporate, and public, primarily in Washington with some in other areas of Virginia. He worked his entire career in his own practice, dealing with both the technical and aesthetic aspects of design. After his death, his drawing were held by relatives.
