Mark Sealey is a British expatriate working and living in Southern California with his artist/writer wife, Roberta Lannes-Sealey, whom he met in 1996, when the web, she and he were much younger.
Mark's interest in computers began in the the early ‘80s when his father suggested that, If we don’t understand how to control them, they’ll creep up behind us and make life unbearable. Have they?
Using the venerable Acorn system until his move to the US, Mark wrote extensively about the BBC and RISC machines. He concentrated chiefly on education, music and productivity/system software; at the time Micronet and Prestel led the way for wide area networking… he published over 2,000 articles for these outlets.
After graduating with a humanities degree, Mark was a teacher for 20 years until 1994 - first in Italy then the UK. Becaming increasingly attracted to the world of information technology as a major contributor to children’s learning and development, he eventually moved to editing the UK’s chief journals in the educational computing. He has always enjoyed freelance reviewing, consulting, editing and writing.
When he moved to the US, he was fortunate enough to find full time employment at a major arts non-profit as a software engineer; though it’s doubtful if there’s a single skill which he was originally hired to use that’s still in daily use.
Mark is also a composer of chamber and orchestral music, music critic, a published poet, photographer and environmentalist with an enthusiasm for fitness, vegan nutrition and long distance running. He is now convinced that only humans’ humility can save our planet.
