LEONARD BERGSTEIN
Zoom Lens—Faculty, Class of 1959 Leonard Bergstein developed the original zoom lens and patented several different variations of his invention. Dr. Bergstein’s approach to the design was done with the help of sophisticated mathematical equations known as Chebyshev polynomials. These equations were
used to develop the proper zoom calibration to enable a photographer to zoom in and focus on an object. Dr. Bergstein’s zoom lens system technology revolutionized photography and film—making zoom lenses standard on almost every camera worldwide.
