I knew Peter well through his work for the Education Division of CSIRO in Victoria, running family science nights. He had designed and built a marvellous collection of equipment that allowed children of all ages to enjoy hands on science, which he was willing to transport and set up for anyone who was interested. I had many enjoyable conversations with him and was amazed by his abilities, truly looking forward to any opportunity to catch up, now alas, gone.
