A second presentation was made that evening. At the
invitation of Ben Hill, Harry Bickhardt, long time
employee of WIP (since 1954!) gave a talk on his time at WIP and how things
were at various times at the Bellmawr plant. It was very fascinating to know
how things were throughout the time he has worked at WIP and the stories he had
to tell were just a great aural picture. We thank Harry for also making the
evening great!
