Webb and Knapp was a real estate development firm.

The company is most famous for developing the Roosevelt Airfield, which was the launching site of the transatlantic flights of Charles Lindbergh and Amelia Earhart. It was also the firm at which famed architect I. M. Pei, first worked, from 1948 to 1956.


The company was founded in 1922 by Robert C. Knapp and W. Seward Webb.

William Zeckendorf joined the firm in 1938 and acquired it in 1949.[1]

In the 1960s, the company filed for bankruptcy protection and Roosevelt Airfield was sold to Corporate Property Investors.[2][3]
