In 1926 Robert W Swift co-founded a binocular importing company called Swift & Anderson.  They also imported weather instruments. In 1959 the name was changed to Swift Instrument Company.  They currently are called Swift Optical Instruments and are a supplier of microscopes and other laboratory optics.  I believe they are a division of Fisher Scientific.
