Wilfrid Noel Bond (27 December 1897 – 25 August 1937) was an English physicist and engineer known for his work in fluid mechanics. He received his Doctor of Science from the University of London, and was a lecturer at the University of Reading from 1921 until his death.[1][2] The Bond number, used in fluid mechanics to characterize the shape of bubbles and drops, is named after him.[3]
Bond is also known for having described, in 1922, an improvement to the first fisheye lens setup[4], previously proposed by Robert W. Wood in 1908[5]. Consisting of an hemispherical lens glass in a pinhole setup, it offered a much simpler and portable setup than its predecessor (which relied on a rectilinear lens installed inside a sealed tank of water) and reduced exposure times[6]. The focal length depended on the refractive index and radius of the hemispherical lens, and the maximum aperture was approximately f/50; it was not corrected for chromatic aberration and projected a curved field onto a flat plate. Bond noted the new lens could be used to record cloud cover or lightning strikes at a given location.
