After graduating, Schade worked at Telephonfabrik A.G. vorm. J. Berliner in
Berlin and
Düsseldorf (1922–1924), and at the Ratig company in Berlin (1924–1925). He then emigrated to the United States to work at
A. Atwater Kent in
Philadelphia (1926–1931). In 1931 Schade joined the Radio Corporation of America (
RCA), where he spent the remainder of his career. From 1944 to 1957, he developed a unified theory of image analysis and specification, including practical methods for measuring the
optical transfer function and noise in optical, photographic, and electronic imaging systems. In 1958 he began a study leading to the
Nuvistor low-noise tubes for television receivers. He received 85 patents. He retired from RCA in 1968, continuing as a consultant until 1974. ==Recognition and awards==
