I was fortunate to have taken Mr. Harvey's course while a student at Penn State in the early '60's. If I remember correctly the course was non-credit, 10 weeks long, given only in the Spring quarter, Saturday mornings for about 3 hours and limited to about 12 students. It focused mainly on tying techniques, rather than on specific patterns and gave me a great tying base to work from. I believe that he started the course in late 1930's.
