Sanford Alexander Moss (August 23, 1872 – November 10, 1946) was an American aviation engineer, who was the first to use a turbocharger on an aircraft engine.[1][2]


Life and career[edit]

He was born 1872 in San Francisco, California to Ernest Goodman Moss and Josephine Sanford.[2] He received his B.S. and M.S. in engineering from the University of California, San Francisco. He received his Ph.D. from Cornell University where he built his first gas turbine engine. After his graduation he went to work for General Electric.[1]

He married Jennie Edith Somerville Donnely on August 23, 1899 in Chicago, Illinois.[2]

In autumn of 1917 William F. Durand, Director of the National Advisory Committee for Aeronautics, received incomplete reports that a French engineer named Auguste Rateau was attempting to develop engines for high altitudes using a turbo-driven air compressor. Durand Remembered Moss as a graduate student who worked on gas driven turbo engines twenty years earlier at Cornell before starting a career at the gas turbine division of General Electric. Durand wrote this letter to the president of GE, E. W. Rice, requesting Moss' services:

"Dear Mr. Rice:
At the present time in connection with the development of the airplane and the Liberty engine for driving same, there is no problem which is perhaps more seriously before the Government officials than that of maintaining at high altitudes the power of the engine. In this connection we are especially desirous of developing the possibilities of a pre-compression of the air before going to the engine carburetor, thus maintaining, as nearly as may be, constant conditions regarding pressure at all altitudes.
In this connection we believe that your Dr. Sanford A. Moss could be of very great service in advising with us regarding the possibilities of pre-compression as applied to this problem, and I have written informally to Dr. Moss inviting his attention to the problem as outlined.
I desire, therefore, to ask your approval of the request, and that, if possible, you will authorize Dr. Moss to give such attention to this problem as may be necessary in order to give us the results of his experience in the study of such matters.
Thanking you in advance for you anticipated cooperation in this matter, I remain, -"[3]

After this turbochargers became Moss' life work.[3]

He died in 1946.[2]
