[1][2][3][4][5] Tom Kremer was a games designer, entrepreneur and publisher, best known for his discovery and popularisation of the Rubik's Cube.
As an octogenarian he founded the publishing house Notting Hill Editions, with the aim of reinvigorating the lost art of the essay.
Following studies in philosophy at the University of Edinburgh, where he met his future wife Alison Emily Balfour, he carried out post-graduate research at the Sorbonne.
Kremer had been living in England and working in games design since the 1960s when he visited a trade show in Germany and saw the Rubik's Cube for the first time in 1979.
His son David recalled: "The cube wasn't a big sensation at the Nuremberg toy fair: it was just a small thing in a backwater section at this huge event."
