Louis Georges Gouy

Louis Georges Gouy (February 19, 1854 – January 27, 1926)^[1] was a French physicist. He is the namesake of the Gouy balance, the Gouy–Chapman electric double layer model (which is a relatively successful albeit limited model that describes the electrical double-layer which finds applications in vast areas of studies from physical chemistry to biophysics) and the Gouy phase.

Gouy was born at Vals-les-Bains, Ardèche in 1854. He became a correspondent of the Académie des sciences in 1901, and a member in 1913.

Topics investigated

His principal scientific work was related to the following subjects:

• The propagation velocity of light waves in dispersive media
• Propagation of spherical waves of small radius
• Distant diffraction (angles of dispersion reaching 150°)
• Electrostatics: Inductive capacity of dielectrics
• Surface charge
• Effect of the magnetic field on the discharge in rarefied gases
• Electrocapillarity
• Emission capacity of absorbent of the coloured flames
• Brownian motion
• Measurement of magnetic susceptibility of transition metal complexes with Gouy balance
• The gouy phase shift, a feature of Gaussian beams
