Hans Bezemer
His first Forth compiler was something published in a british magazine in 1984. After hours of typing, it still didn't work.
His next Forth compiler was Artic Forth for the Spectrum 48K. He got to port it to his Betadisk interface, but not much more.
After switching to the IBM/DOS world in 1987 he got F83 and FPC, but didn't like Forth-83 at all. So he dumped Forth for C.
Years later, in 1994 he decided to make his own Forth compiler - but at his own terms. No Forth engine, conventional compiler technology. That became 4tH.
Hans works in IT as a Business Consultant for a large European bank. He's also known for his love of the music of 'The Doors'.
