Son of a bus driver ....

My mother always insisted he was a “coach driver” but no matter, from my father I inherited a love of cars and driving. I was born in England but apart from growing up and marrying Ros in the UK, since 1975 the family home has been in one of the main bulb-growing area of The Netherlands. Ros and I hold dual Dutch and British nationality - so no BREXIT worries!

I worked 25 years for an Oil Major – ending up as a Global I.T. Strategist. Retiring early, Ros and I enjoy travelling and watching our married daughter Siân’s family grow up – we have a granddaughter Zara and a grandson Owen.

By harnessing the WWW to share my slide rule collection and my published articles will, I hope, provide a useful source of information to other avid collectors or just surfing visitors to the site.

I am a member of the UK Slide Rule Circle, the Dutch Circle for Historical Calculating Instruments and the German Rechenschieber-Sammler (RST) Group. I am also a Fellow and 2011 Award winner of the American Oughtred Society.
