About Us

History:
In 1908, C.F. Iszard and J. Henry Warren organized the Iszard-Warren Company to design, manufacture and sell precision surveying, engineering and scientific instruments. In 1913, our quickly expanding company became known as the Warren-Knight Instrument Company. For many years, W-K manufactured and operated at its Center City location. In 1963, Warren-Knight moved to its current location in Northeast Philadelphia.
