Over a span of twenty-five years, I had the privilege of an extraordinary association with Charles Seeger. It began with an introduction by Jaap Kunst, in 1954, and ended with a letter dictated by Seeger and typed by his secretary (but still unsigned), a few days before his death in February, 1979. In our first meeting he was a teacher. In his last letter he was a warm concerned friend, and still a teacher. To say he is missed would be as redundant as saying one misses a brother, a father, a comrade-in-arms, a colleague, a best friend.
