Thomas Ranken Lyle

Sir Thomas Ranken Lyle FRS (26 August 1860 – 31 March 1944) was an Irish-Australian mathematical physicist, radiologist, educator, and rugby player.

Lyle was born and educated in Ireland before emigrating to Australia to take up a professorship at the University of Melbourne. There he was a pioneer in the use of X-rays as a medical tool. The Thomas Ranken Lyle Medal is awarded in his name to honour Australian achievements in Physics and Mathematics.

In his earlier years in Ireland he was a rugby union forward of some note, who played club rugby for Dublin University and international rugby for Ireland.

Career Lyle was born in Coleraine, Ireland in 1860, the second son of Hugh Lyle, a well-to-do landowner. He was educated at Trinity College, Dublin, graduating in 1883 with full honours and student medals for his work in mathematics and physics. He received his MA in 1887, and continued his studies in advanced physics and mathematics. By 1889 he had emigrated to Australia, and at the age of 29, took up the position of the chair of natural philosophy at the University of Melbourne. In June 1896 he was invited to take a photo of a patient who had a needle embedded in their hand. The resulting 'shadow photograph', as the images were then known, allowed doctors to remove the needle with a single incision. a member of the Federal Munitions Committee, and president of the Industries Exemption Advisory Committee.

On 7 September 1995, Lyle was one of seven scientists to be honoured with his image appearing on an Australian postage stamp. Lyle appeared on a 45-cent stamp, along with fellow pioneers of X-ray research Father Joseph Patrick Slattery and Walter Drowley Filmer.

Rugby career While a student at Dublin University, Lyle played rugby union for the university team. He was impressive enough at university level to bring himself to the notice of the Irish selectors, and was capped for his first international match in the 1885 Home Nations Championship. Lyle played in both Irish games of the 1885 tournament, away loses to England and Scotland. The Scotland game was originally played in Ireland, but weather conditions forced the match to be abandoned after 20 minutes. Lyle played in both the original game and the replay, which sometimes incorrectly causes Lyle to be credited with six international caps. Despite a poor record the previous season, Lyle was reselected for the 1886 tournament, playing in a single game, a one-try loss to England.

He was captain of the Ireland team for a season and was leader of the forwards the year Ireland won the Triple Crown.

His final group of internationals were for the 1887 Home Nations Championship. Lyle was selected for the encounters with England and Scotland, which included his only winning international game when Ireland defeated England by two goals to nil. Lyle had one final role during the 1887 campaign when he was selected to referee the encounter between England and Scotland. His rugby career ended not much later when he suffered a knee injury which affected his health for the rest of his life.
