A new weekly series for Irish Times Abroad profiles an Exraordinary Emigrant from Irish history, based on entries from the Royal Irish Academy’s Dictionary of Irish Biography. The members adopted nicknames (Tyndall’s was Xcentric and Frankland’s Xpert), and each defended different aspects of the theory. The resulting clouds of small particles scattered visible light to produce colours including the blue of the sky, now known as “Tyndall blue”. Tyndall also held a chair of physics in the Royal School of Mines (later Imperial College), where he lectured from 1859. Based on Norman McMillan’s biography of John Tyndall in the Royal Irish Academy’s Dictionary of Irish Biography
