1971, the year I met him. He was the founder of Plainsman Clays. My dad had just built the factory for him and I began working there in 1972. He was a well known potter and sculptor at the time. He got me started along the fascinating road of understanding the physics of clays. He was a true "plains man", interested in the geology (notice the skulls, these inspired the Plainsman logo). He got me started doing physical testing of raw clays (that he was finding everywhere). I was blown away by the fact that I could assess a completely new material and judge its suitability for many types of ceramic products and processes by doing the simple physical tests he showed me. It got started writing software to log the data for that back in the 1980s, that eventually led to digitalfire.com and Insight-live.com.
