Pete Rugolo was not a trombonist but did start his music career on baritone horn, which is close enough.
More importantly, he was one of my favourite arrangers of all time, after WW2 writing most of the book for the Stan Kenton Orchestra, which was one of the most musically progressive big bands of the era. Also notable to trombonists for creating the arrangements for the album "The Four Freshmen and Five Trombones", which is one of my favourite recordings of all time. Rugolo also wrote arrangements foe my favourite female vocalist June Christie, including her albums, 'Something Cool', 'The Misty Miss Christy', 'Fair and Warmer!', 'Gone for the Day' and 'The Song Is June!'.List of Jazz Musicians with birthday on 25th December:
