On December 10, 2013, the preservation world lost one of its passionate leaders in digital imaging and preservation of photographic collections.
I only had the pleasure of crossing paths with Steve once when I was working in Washington, D.C. back in the 90s. He invited me and a colleague to tour his digitization labs at NARA II. He was the Preservation and Imaging Specialist at NARA, where he was responsible for establishing and managing the digital imaging labs and had endless projects and responsibilities, yet he took the time to show us around and talk about the difficulties with digitization and digital preservation. We were just starting to look at digitizing collections and had the most basic questions like guidelines for image capture, automating batch image processing, and best image correction techniques, certainly nothing as complicated as he was faced with, but he took the time to actually show us how to do these things. We did not want to waste his time, but he had so much knowledge we wanted to tap into and he never rushed the conversation. He was a wonderfully patient teacher and advocate and he will be missed.
