Early life and education
Watt Wetmore Webb was born on August 27, 1927, in
Research career
After his doctorate, Webb returned to Union Carbide as assistant director of research.
In the early 1970s, Webb collaborated with Elliot Elson to develop a method to monitor the kinetics of chemical reactions, focused particularly on the binding of ethidium bromide to DNA. The result was the development of fluorescence correlation spectroscopy, which they described in a series of papers from 1972 to 1974.[6][a]
From 1983–1988 Webb served as director of the college's School of Applied and Engineering Physics.[1] In the late 1980s, Webb – along with then PhD student in his laboratory Winfried Denk – built the first multiphoton microscope.[1]
In 1998, Watt was named to an
He has directed the NIH Developmental Resource for Biophysical Imaging Opto-Electronics for the last 20 years. He was on the board of directors and executive committee of the Cornell Center for Technology, Enterprise, and Commercialization, was affiliated with the university's Biophysics Program, the Cornell Center for Materials Research, the Nanobiotechnology Center and served on the Executive Committee of the Neuroscience Focus Area. He was a visiting scholar at
He was a fellow of the American Physical Society (APS) and the American Association for the Advancement of Science, a founding fellow of the American Institute for Medical and Biological Engineering, and an elected member of the National Academy of Engineering (1993), the National Academy of Sciences (1995), and the American Academy of Arts and Sciences.[1]
He also received several awards for his work, including the American Physical Society's
Watt retired from active research as an
He published over 310 papers in solid state and chemical physics and in biological physics; with 22 U.S. patents plus many foreign patents. He was active as a consultant and in various national advisory committees and professional societies.
His doctoral students include Malcolm Beasley, Winfried Denk, Neil Gershenfeld, and David W. Tank.[14]
Webb died on October 29, 2020, in New York City at the age of 93.[1]
FCS and MPM
Professor Webb pioneered the techniques of Fluorescence Correlation Spectroscopy (FCS) in 1972[15] and Multiphoton microscopy (MPM) in 1990.[16] FCS enables single-molecule detection in solutions at nanomolar concentrations and provides temporal resolution of the dynamic processes of individual molecules signaled by their fluorescence. FCS reveals molecular mobility, conformational fluctuations and chemical reactions in solutions and allows the detection of extremely sparse molecules and particles. In situ measurements of the dynamics of fluorescence flicker by FCS, photobleaching, phototoxicity, and induced fluorescence are being used to discern dynamics of biological processes and molecular mechanisms of disease. Multiphoton excitation in laser scanning fluorescence microscopy provides for high resolution, high signal-to-noise imaging in living cells and deep in turbid tissues in vivo and significantly reduces photodamage and minimizes image degradation due to scattering and autofluorescence. His laboratory at Cornell University continues to extend the frontiers of these technologies, now for example extending MPM and FCS to imaging molecular processes within the cellular nucleus for gene expression in vivo. Recently initiated is the development of technology for introduction of MPM into Medical Endoscopy for in vivo, in situ real time diagnostics.

Personal life
Webb was an avid sailor, together with his wife Page Chapman – whom he met sailing[18] on the Charles River while Webb pursued his bachelor's degree.[9][19] Together they raced sailing yachts across the northeast well into their 70s.[19] They had three children together, a son in 1954, and twin boys in 1956.[19]
