  ==Thanks for your contributions!== Thanks very much for your contributions, which I've enjoyed reading through very much this evening - a very congenial mix of tech businesses, recreational mathematics and bibliographic interest! I've added some categories etc. but hopefully haven't taken anything away from your pages. If you're using John Lauris Blake's General Biographical Dictionary to find individuals lacking a wikibio, it looks as if it's worth having a good look for the name forms which are most commonly used today in case they're different. Best wishes,
