Steve Meyerowitz was known as "The Sproutman".  The Sproutman site includes the short video shown below and says:
 

Steve was pronounced “Sproutman®” by Vegetarian Times Magazine in a 1979 feature article that explored the why’s and wherefores of his 100% sprout diet..... Steve got interested in natural foods after a 20-year effort to correct chronic allergies and asthma with conventional medicine.  He  made dramatic changes in his diet and within two months of eating a strict “living foods,” vegetarian diet, his lifelong symptoms vanished. He continued to practice a 100% raw foods diet (nothing cooked, packaged, canned, frozen, or processed) for five years.
 

Steve’s innovative kitchen gardening techniques and the cuisine he developed from them gave rise to a “School for Sprouts.” He began teaching indoor gardening in New York City. He called his no-cooking school, The Sprout House, since so much of his cuisine included vegetables from his kitchen garden-sprouts. Steve invented two sprouters, The Flax Sprout Bag and a greenhouse called Sproutman’s Kitchen Garden Salad Grower. His books on sprouts include Sprouts the Miracle Food.
