Emil Wolf - Life and Career

Life and Career

Wolf was born in Prague, Czechoslovakia. He was forced to leave his native country when the Germans invaded; After brief periods in Italy and France (where he worked for the Czech government in exile), he came to the United Kingdom in 1940. He received his B.Sc. in Mathematics and Physics (1945), and PhD in Mathematics from Bristol University, England, in 1948. Between 1951 and 1954 he worked at the University of Edinburgh with Max Born, writing the famous text-book on Optics now usually known simply as 'Born and Wolf'. After a period on the Faculty of the University of Manchester, he moved to the United States in 1959 to take a position at the University of Rochester. He is currently (2012) the Wilson Professor of Optical Physics at the University of Rochester. He is a naturalized US citizen. He was president of the Optical Society of America in 1978. Wolf now resides in Cloverwood in Pittsford New York with his wife.

He also predicted a new mechanism that produces redshift and blueshift, that is not due to moving sources (Doppler effect), that has subsequently been confirmed experimentally (called the Wolf Effect). Technically, he found that two non-Lambertian sources that emit beamed energy, can interact in a way that causes a shift in the spectral lines. It is analogous to a pair of tuning forks with similar frequencies (pitches), connected together mechanically with a sounding board; there is a strong coupling that results in the resonant frequencies getting "dragged down" in pitch. The Wolf Effect can produce either redshifts or blueshifts, depending on the observer's point of view, but is redshifted when the observer is head-on. A subsequent 1999 article by Sisir Roy et al. have suggested that the Wolf Effect may explain discordant redshift in certain quasars Ref.
