This chapter discusses Jules Janick, whose career has been intertwined with enormous changes in horticultural science and plant breeding. More than any other person in the U.S. in the last 60 years, Jules Janick has doggedly brought horticulture into the scientific realm. Jules Janick was the editor of fourteen volumes of HortScience from 1970 to 1983, and eight volumes of the Journal of the American Society for Horticultural Science from 1976 to 1983. He has edited ten volumes of Acta Horticulturae for the International Science of Horticultural Science (ISHS), and two volumes of Scripta Horticulturae. He also founded and single-handedly edited forty volumes of Plant Breeding Reviews and 43 volumes of Horticultural Reviews, which stand as an extraordinary accomplishment in twentieth century horticulture. Many of his texts still form the foundation for introductory horticulture and crop science courses offered around the world. Janick is also the co-editor, with James Moore, of a number of volumes on fruit breeding, including Advances in Fruit Breeding and Methods in Fruit Breeding. Janick holds six utility patents and 23 plant patents, and one Plant Variety Protection (PVP) certificate. Professor Janick has been a faculty member at Purdue University for over sixty years.
