Kenn Duncan (1923-1986) was similar in many ways to Roy Blakey.  Both were ice skaters at one time who turned to photography later.  Duncan became well known in New York in the period of 1968-1980 for his photos of dancers and the casts of Broadway shows.  Although he published two volumes of photos with"nude" in the title, they would seem mostly to be semi-nudes, and I have had trouble finding many full frontal Kenn Duncan photos.  (Anyone willing to share some will be credited and given profuse thanks.)  So today is Kenn Duncan day.
