Roy Harrod

Sir Henry Roy Forbes Harrod (13 February 1900 – 8 March 1978) was an English economist. He is best known for writing The Life of John Maynard Keynes (1951) and for the development of the Harrod–Domar model, which he and Evsey Domar developed independently. He is also known for his International Economics, a former standard textbook, the first edition of which contained some observations and ruminations (wanting in subsequent editions) that would foreshadow theories developed independently by later scholars (such as the Balassa–Samuelson effect).

Biography
Harrod was born in London to businessman Henry Dawes Harrod and novelist Frances Forbes-Robertson. He attended St Paul's School and then Westminster School. Harrod attended New College in Oxford on a history scholarship. After a brief period in the Artillery, in 1918 he gained a first in literae humaniores in 1921, and a first in modern history the following year. Afterwards he spent some time in 1922 at King's College, Cambridge. It was there that he met and befriended Keynes.

After moving back to Oxford, he became a Student (i.e., Fellow) and Tutor in economics at Christ Church. He held the fellowship in modern history and economics until 1967. He remained in contact with Keynes until Keynes's death in 1946, and was later his biographer (1951). Harrod was additionally a Fellow at Nuffield College 1938 to 1947 and from 1954 to 1958.

At Oxford Harrod was part of the Railway Club, which included: Henry Yorke, Roy Harrod, Henry Thynne, 6th Marquess of Bath, David Plunket Greene, Edward Henry Charles James Fox-Strangways, 7th Earl of Ilchester, Brian Howard, Michael Parsons, 6th Earl of Rosse, John Sutro, Hugh Lygon, Harold Acton, Bryan Guinness, 2nd Baron Moyne, Patrick Balfour, 3rd Baron Kinross, Mark Ogilvie-Grant, John Drury-Lowe.

During the Second World War, he was briefly in Winston Churchill's "S-branch" – a statistical section within the Admiralty.

At the 1945 General Election, he stood as Liberal candidate for Huddersfield and finished third of three candidates, with 16.2% of the vote.

In 1966, Harrod, was the 2nd winner of the prestigious Bernhard-Harms-Preis. After retiring in 1967, he moved to Holt, Norfolk.

Interviewed for the book Authors take Sides on Vietnam, Harrod declared himself a supporter of the American military campaign in Indochina.

Assar Lindbeck, the former chairman of the Nobel Prize Committee, wrote that Harrod would have been awarded a Nobel Memorial Prize in Economic Sciences if he had lived longer.

Harrod married Wilhelmine "Billa" Cresswell (1911–2005), step-daughter of General Sir Peter Strickland, in 1938. One of their sons was Dominick Harrod, an economics correspondent for the BBC.

The Life of John Maynard Keynes
After the death of his Cambridge friend and colleague, the economist John Maynard Keynes, in 1946, Harrod and Austin Robinson wrote a lengthy obituary of Keynes for The Economic Journal. At the encouragement of Geoffrey Keynes, Harrod then undertook the task of writing a major biography of Keynes. The Life of John Maynard Keynes was published to widespread acclaim in 1951, at a time when most of Keynes's family and friends were still alive.

With the post-war influence of so-called Keynesian economics and then challenges to it, cultural interest in the Bloomsbury Group, and the publication of thirty volumes of The Collected Writings of John Maynard Keynes in the 1970s and 1980s, high interest in Keynes's life led to further biographies, most prominently by Robert Skidelsky and Donald Moggridge, and to detailed studies such as by Donald Markwell on Keynes and international relations. These works have corrected and added details to the Keynes depicted by Harrod, and Skidelsky in particular has contrasted his account of Keynes with what he has depicted as Harrod's hagiography.
