Widener Director and Chief Executive Officer, announced today that he plans to retire in early 2022 after thirteen years of service at the Philadelphia Museum of Art. Rub, who will turn 70 in early March, has led the museum since September 2009. During his tenure, the museum has undergone a significant transformation. A major phase of the Facilities Master Plan designed by Frank Gehry, the Core Project, was completed in late spring 2021 after a decade of planning and four years of construction. Hailed as a thoughtful and nuanced response to the architectural character of the museums landmark main building, the Core Project represents the largest increase in public and gallery space to this facility since it was opened to the public in 1928. Rub also initiated several other capital improvements (listed below), among them the renovation of the Rodin Museum and its gardens, that have significantly improved the presentation of the museums permanent collections and enhanced the experience of its visitors.
