Alpha was a science fiction fanzine by Jan Jansen and Dave Vendelmans.
Alpha was published in Belgium in the 1950s. It was the official organ of the Antwerp Science Fiction Fan Club. The first issue appeared in Summer 1953.
Jan Jansen and Dave Vendelmans were in contact with fans in Britain, and some fans were stationed with the British army in Belgium, so Alpha began as a dual language fanzine, featuring both Dutch and English, and was probably the first science fiction fanzine to be published in Europe, outside of the UK. Aside from Belgium fans, it had readers in the Netherlands, the UK, and the U.S.A. It ended up being printed entirely in English.
Dave Vendelmans emigrated to Canada in 1956 and Alpha ceased publication at that time. About 23 issues were published in total between 1953 and 1956.
