Martin Alper co-founded the british games publisher Mastertronic in 1983. When Mastertronic was later purchased by Richard Branson, Alper became president of the new company. This is a transcript of an interview conducted by phone in 2013. The interview was conducted as research for an article on The 7th Guest and The 11th Hour, so the focus of the interview is on the story behind these games. Martin Alper sadly passed away in 2015.
