1048 Omar Khayyám - Persian poet, mathematician and astronomer. He produced a work on algebra that was used as a textbook in Persia until the 1900s. In geometry, he studied generalities of Euclid and contributed to the theory of parallel lines. Around 1074, he set up an observatory and led work on compiling astronomical tables. His contributions to other fields of science included developing methods for the accurate determination of specific gravity. He is known to English-speaking readers for his "quatrains" as The Rubáiyát of Omar Khayyám, published in 1859 by Edward Fitzgerald, although it is now regarded as an anthology of which little or nothing may be by Khayyám
