The Fox Theatre at 1600 Market Street in downtown Philadelphia opened on November 26, 1923. The 2,400 seat theatre was designed by famed theatre architect Thomas Lamb. The Fox closed in March 1980. Shortly thereafter the fixtures were sold. I was part of a four man team sent from Columbus Ohio, in May 1980, to salvage the light fixtures, Jed Ellis and Todd Bemis were also part of the team. I especially remember hauling down the huge auditorium chandelier and dismantling it.
