Emil Wolf — summary
Emil Wolf (July 30, 1922 – June 2, 2018) was a Czech-born American physicist known for shaping modern optical theory. Born in Prague, he became best known for rigorous work in physical optics and for coauthoring the standard textbook Principles of Optics. Biographical material and career summaries are available in many reference sources (biographical overview).
Research areas and themes
- Physical optics — development of analytic methods for diffraction and wave propagation.
- Diffraction — theoretical descriptions that extend classical treatments to partly coherent fields.
- Coherence — studies of spatial and temporal coherence that underpin statistical optics.
- Spectroscopy and the behavior of partially coherent radiation, including spectral features that arise from coherence properties.
- Direct and inverse scattering theory, linking measured fields to object properties and vice versa.
Wolf combined mathematical rigor with physical insight to build frameworks now taught across optics and photonics. His analyses clarified how partial coherence affects interference, imaging, and spectral measurements. Some spectral-shift phenomena observed in partially coherent light are often associated with ideas that emerged from his work.
Textbooks and lasting works
One of Wolf's most widely used contributions is his collaboration with Max Born on Principles of Optics, commonly cited as "Born and Wolf." That book set a standard for graduate-level treatments of electromagnetic theory in optics and remains a central reference for researchers and students studying optical fields and wave propagation.
Career, influence and legacy
Wolf spent much of his professional life in the United States as a research scientist and educator, influencing generations of physicists through publications and teaching. He was a prominent figure at institutions and conferences that shaped 20th-century optics. He died in Rochester, New York on June 2, 2018.

Notable facts and distinctions
- Wolf is widely associated with the modern theory of partial coherence and its practical consequences for imaging and spectroscopy.
- His work bridged theoretical electrodynamics and experimental optics, making statistical approaches commonplace in photonics research.
