John was an amazing and compassionate geoscientist and mentor.  His contribution to our field will endure forever.  Perhaps just as important to that contribution in terms of his books, papers, and wisdom, was his ability to encourage young people.  In a quiet and unassuming way, John had the ability to give advice, inspire, and encourage students and young professionals around him.  This gift of his appeared in the classroom, on the outcrop, at professional meetings, and around the department.  Thank you John, for your kind words when I was a graduate student attending the first HKT meeting in Leicester in 1985.  Thank you also for all of the mentoring during my post doc in Zurich in 1988-89 and for yours and Dorothee’s friendship thereafter.  You are greatly missed already.
