The Trinity economist and former research professor with the ESRI joined George Hook on High Noon today.
Tributes have been pouring in for TK Whitaker, once voted Irishman of the 20th Century, following his death at the age of 100.
Trinity's adjunct professor of economics John Fitzgerald, who also knew Whitaker personally, joined George to talk about his legacy.
He has been described as the greatest civil servant Ireland has ever seen, yet is someone that many may not know that much about exactly what he did, and how much he achieved for Ireland.
When asked what made him so important, Fitzgerald's first response was interestingly that 'he was his own man'.
Whitaker wrote the blueprint for economic stability and prosperity, Economic Development. Free trade was at its heart, and he worked diligently on it with Taoiseach Sean Lemass from 1959 to 1966.
He also helped broker the historic visits of Taoisigh Lemass and Jack Lynch to Stormont in 1965 and 1967 respectively.
