A sign on the corner of 1st Avenue and East 4th Street in Manhattan was renamed at a ceremony this summer in honor of  Frieda Zames, the late NJIT Associate Professor Emerita of mathematics and disability rights advocate who played a pivotal role in making the NJIT campus accessible to persons with disabilities. Zames, who taught math at NJIT for 27 years, died in 2005 at the age of 72.  Her three decades of advocacy also included pushing for access to the 88th floor observatory of New York's Empire State Building, which is now accessible.
