William Edward Thrift, Irish academic and politician who serves as the 37th Provost of Trinity College Dublin (TCD) and a Teachta Dála (TD) for the Dublin University constituency from 1921 to 1937, dies in Dublin, on April 23, 1942.

Thrift was born in Halifax, West Yorkshire, England, on February 28, 1870, one of at least two sons and two daughters of Henry George Thrift, civil servant, and Sarah Anne Thrift (née Smith). The family moves in his childhood to Dublin, where his father is an officer in the Inland Revenue.

He is educated at The High School, Dublin, and enters Trinity College Dublin in 1889 with a second sizarship in mathematics, and commences a highly distinguished university career, scoring firsts in several examinations and winning numerous prizes. Elected fellow in mathematics and experimental science, and in mental and moral philosophy in 1896, he becomes Erasmus Smith’s Professor of Natural and Experimental Philosophy at TCD from 1901 to 1929. He is awarded a Doctor of Science (DSc) in 1936. He is appointed Provost of Trinity College Dublin in 1937, serving until his death in 1942.

Thrift is also active in politics. He is elected to the House of Commons of Southern Ireland at the 1921 Irish elections, representing the Dublin University constituency. As an independent Unionist, he does not participate in the Second Dáil. He is re-elected for the same constituency at the 1922 Irish general election and becomes a member of the Third Dáil. He is re-elected at the next five general elections until 1937 when he retires from politics.

While rarely speaking on controversial issues, Thrift opposes the 1925 legislation banning divorce, which he describes as an infringement of individual and minority rights, and a betrayal of commitments made by Arthur Griffith during the Anglo-Irish Treaty debates. His capable service on various Dáil committees is recognised by his election as Leas-Ceann Comhairle (deputy speaker). A long-serving council member of the Royal Dublin Society (RDS) (1902–42), he is a commissioner of charitable donations and bequests, and financial adviser to the General Synod of the Church of Ireland. He sits on the governing boards of the Erasmus Smith schools and of the Incorporated Society for Promoting Protestant Schools in Ireland.

Thrift’s portrait is painted by Leo Whelan. He marries Etta Robinson, a daughter of C. H. Robinson, a medical doctor, and they have three sons and three daughters. He dies at the provost’s house, Trinity College Dublin, on April 23, 1942. He is buried at Mount Jerome Cemetery, Harold’s Cross, County Dublin.
