A man with a keen sense of the future of the profession of plant pathology, he assemblecl a large group of students and colleagues at the University of Wisconsin into an effective center for research in forest pathology, crown gall clisease, and plant tissue culture. The pioneering research on crown gall and on plant tissue culture that he and his colleagues carried out for many years provided some of the basis for mo(lern plant genetic engineering.

Young Riker attended public school in Alliance and finished high school in Moundsville, West Virginia, where he (leveloped an early interest in biology. At different times after high school graduation, however, he worked for the Royal Three Barrel Gun Company, he was an automobile repairman ant!

Keitt's responsibilities included a wide variety of problems affecting the orchard fruit industry in Wisconsin; among these were fireblight anct crown gall of apple, diseases that to this clay have proven refractory to control. By the time he arrived at Wisconsin, Riker was unusually well qualified to work on bacterial diseases and Keitt was happy to hand him the crown gall problem.

At a meeting of the American Phytopathological Society, George McNew, a rather forceful inclividual who later became head of the Boyce Thompson Institute, stated that bacteria could be purified by the simple procedure of cliTution plating. Riker insistec!

Riker brought into his program a large number of students who went on to work on tree diseases. The emphasis was on the mechanisms for spread of pathogens that causecl oak wilt, Dutch elm disease, white pine blister rust, poplar canker, and maple dieback, among others.

Riker also was instrumental in obtaining support from the Wisconsin Legislature for a new staff member who would work on Dutch elm disease, a disease that had decimated urban shade trees throughout the eastern seaboard in the Uniter!

Carl Beckman, one of joyce's most preeminent students, recalls that as several students completed work on the road that led to their living quarters at the Rapids, someone put up a sign that named the road "Opportunity Road." Joyce, who often visited the station with dignitaries in tow, apparently never quite understood!

The Riker Conference Room, as it is known today, remains a wonderful memorial to a man of keen insight whose contributions were of immeasurable benefit to the plant sciences. In his lifetime, Joyce received many awards and honors in recognition of his contributions.
