安永 一 (1901-1994) Go writer, very strong amateur player.
Although he continued as an amateur, his status was of a professional who didn't claim the title. When he was granted an 8 dan diploma, Go Seigen quipped that it was unclear whether he was an 8 dan amateur or 8 dan professional ( source: John Fairbairn). He played in the World Amateur Go Championship at age 78 as an appointed representative.
He trained many future professionals.
Famous for being able to give more handicap stones to amateurs than professionals with a formally higher rank. (source: Go World, issue 13) tderz
