Bruce Tharp, Ph.D.
Tharp Food Technology

At the beginning of 1997 Bruce started a new direction in his lifetime of involvement in the ice cream industry. That was not in any way a "retirement", since it was his intention to continue his professional activities at about the same level of intensity as before, with a major focus on ice cream.

There were two major reasons why he wanted to do that. First, he was eager to continue to enjoy the satisfaction of applying and communicating my knowledge of the fascinating and challenging technical and scientific complexities of ice cream. Second, he wanted to keep on experiencing the delight of being associated with an industry in which individuals are almost universally friendly and a pleasure to know. Since then he has enjoyed ongoing activities in assignments involving the realm of ice cream and related products. Those assignments have taken me around the world to participate in ice cream-oriented activities in North and South America, Europe, the Middle East, Australia, and throughout the Pacific and Southeast Asia area.

He has also continued to enjoy his ancillary professional activities, including: Adjunct Professorship of Food Science at Penn State; chief ice cream judge at the Intercollegiate Dairy Products Evaluation Contest; and major lecturer at academic ice cream short courses.

His ice cream roots go back to my childhood. Tharp grew up in the ice cream business, and have never strayed very far from it. From his earliest days in the Tharp's Ice Cream plant his father instilled in me an ardor to make the very best ice cream possible, and he taught me a lot about how to do that.
