Optique physiologique. Tome troisieme, L'espace visuel (Physiological optics Volume 3. Visual space)

Historical Significance: Yves LeGrand (1908-1986) was a prominent French researcher and writer in the field of physiological optics. He wrote a 3 volume text in the French language on physiological optics 'Optique physiologique. Tome premier, La dioptrique de l'oeil et sa correction; Tome II, Lumiere et couleurs; Tome troisieme, L'espace visuel. The first volume was published in 1946 with the later volumes and several editions appearing up to 1972. He was highly regarded in the fields of visual optics and lighting and was awarded the Tillyer medal by the Optical Society of America. He was active in the CIE and was ambitious to be its President but was not so elected when he put his name forward at the 1971 CIE conference in Barcelona. He was the first to propose using interference fringes to measure retinal visual acuity independent of the optics of the eye (See Charman and Simonet Ophthal Physiol Optics 1997; 17: 164-168). Volume 2 was published in English in 1957 under the title Light Colour and Vision and was used extensively as a text book in teaching physiological optics to second year optometry students at Melbourne. Volume 3 was also published in English translation.
