Hermenegildo Arruga (1886-1972) of Barcelona, Spain, was an internationally renowned ophthalmologist and one of the first to practice and improve on Gonin's technique of retinal detachment repair. In 1950, he was awarded the Gonin Medal, which is the highest award of ophthalmology.
In 1970, a commemorative medal of Arruga was struck by Calico of Barcelona, Spain. The obverse depicts the bust of Arruga facing ahead and slightly left. The reverse depicts rays of light in the sky coming through clouds; “ . . . Et Facta Est Lux,” or translated, “and there was light,” from Genesis, is the reverse inscription.
