20135 Juels           Discovered 1996 May 7 by P. G. Comba at Prescott.
Charles W. Juels (b. 1944) of Fountain Hills, Arizona, is a public health physician/psychiatrist and an amateur astronomer who discovered and demonstrated that hunting minor planets can be an addictive activity. In only a year and a half he has been credited with the discovery of 65 numbered objects.
