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!
