Little is known of J. Defert, including his full name. He lost one match in 1896 to [Demetrius Casdagli] in menâs singles. Defert competed for the Racing Club de France. There was a RenÃ© Defert who was secretary of the lawn tennis section of Racing Club de France in that era, and may have been a relative, or possibly even the Olympian, but we cannot confirm that.
