Person: Allman, George Johnston
George Allman was an Irish professor, mathematician, classical scholar and historian of ancient Greek mathematics.
Mathematical Profile (Excerpt):
 George Allman studied both pure and applied mathematics at Trinity College, Dublin, and graduated in 1844 coming first equal among the First Class students (with Samuel Haughton who became professor of geology at Trinity College) and winning the gold medal for mathematics.
 In the same year of 1853 Allman was appointed as Professor of Mathematics at Queen's College, Galway.
 Among the articles Allman contributed to the ninth edition of the Encyclopaedia Britannica were those on Thales, Pythagoras, Ptolemy and other Greek philosophers.
 However, Allman's most significant contribution was Greek geometry from Thales to Euclid published in Dublin in 1889.
 Allman developed methods of deduction of historical information which have proved fundamental in discovering information of the type described in our articles How do we know about Greek mathematics?
Born 28 September 1824, Dublin, Ireland. Died 9 May 1904, Dublin, Ireland.
