She trained at the Indiana University’s famous Kinsey Institute for Research in Sex, Gender and Reproduction, and at the Masters and Johnson Institute in St. Louis.

A frequent television and radio talk-show guest on everything from geriatric sex to child abuse, Tanner had a busy private practice treating transsexuals, fetishists, depressives, and uptight married couples.

A memorial service to celebrate Libby Tanner’s life will be held at 1p.m. on Sept. 9 at Blasberg Rubin Zilbert Funeral Home, 720 71st St., Miami Beach; 305-865-2353.
