John Wisniewski Spirit award

June 2005

OpenVMS Symposium (advanced technical bootcamp), HPE OpenVMS Engineering, Nashua, New Hampshire, USA

The John Wisniewski Spirit Award

OpenVMS Engineering created this award in 2004 in memory of a larger-than-life guy called John Wisniewski. He was a well-known and passionate OpenVMS expert who poured huge amounts of energy into his teaching, writing and consulting work. John was the guy who started the OpenVMS Hobbyist programme and who trounced all-comers at DEFCON with an impregnable OpenVMS system.

Previous recipients are Brian Schenkenberger and Al Meier. This years recipients are Colin Butcher and Kerry Main.

Colin was presented with the John Wisniewski Spirit Award by Ann McQuaid (head of HPE OpenVMS Engineering) at the HPE OpenVMS Symposium in June 2005. This award from peers and colleagues within the OpenVMS community around the world recognises the outstanding contribution, quality and value of his work over many years.

On a more personal note - it came as a huge surprise and it is a wonderful thing to have received. Thank you.
