Why Is David L. Fried Influential?

According to Wikipedia, David L. Fried was an American scientist, best known for his contributions to optics. Fried described what has come to be known as the Fried Parameter, or r0 . The Fried Parameter is a measure of the strength of the turbulence in the atmosphere of Earth. The turbulence causes what is known as seeing in astronomy and usually limits the optical resolution of ground-based telescopes and the detail in their images of astronomical objects. The Fried Parameter describes the smallest diameter of a telescope aperture at which the image fidelity starts to suffer significantly from turbulent airflows in the atmosphere of Earth. The Fried Parameter may change quickly on the time scale of minutes, or less. Typical values for the Fried Parameter in the visible spectrum may range from less than one centimeter to some tens of centimeters at good astronomical sites.
