Drawing on his studies in biochemistry, Dr. John Ansel Armstrong Thomson developed SUPERthrive in 1939. The next year he received the Science & Industry's only Gold Medal at the San Francisco World's Fair Golden Gate International Exposition for his SUPERthrive. Thomson accumulated other awards throughout the years and continued to run The Vitamin Institute, selling SUPERthrive to professional and individual growers across the world for the next 71 years until his passing in 2011. He credited his wife, June Hummel Thomson, for his endurance and as his muse for over sixty years.
