Henry was a very dedicated and talented photographer. His work and approach to shooting climbing inspired Tom Frost and others to pursue their own work. Some of Henry's photos hanging in Hobie Destabeler's house inspired Tom to start climbing in the first place. Henry became Tom's mentor.
Henry wrote an article entitled "Climber's Camera" for the 1962 Sierra Club Bulletin.
Thanks again to Bill Amborn for sending his SCBs my way!
