Denis Brogan was born in Glasgow, the eldest son of Denis Brogan (1856–1934), a master tailor, and Elizabeth Toner. His father was originally from
County Donegal, and was a liberal-minded pro-Boer and Irish nationalist who, at one point, served as head of the Glasgow branch of the
United Irish League, while his mother was a sister of
John Toner, Bishop of Dunkeld. The younger Brogan was educated at St Columcille's Roman Catholic School, Rutherglen, and
Rutherglen Academy. Having initially been cajoled by his parents to study medicine at the
University of Glasgow, he switched to an arts degree following a series of low marks in his examinations, graduating MA Hons. in 1923. Brogan subsequently studied at
Balliol College, Oxford, where he obtained a further degree in history in 1925. He then spent an additional year studying American politics at
Harvard University on a
Rockefeller Research Fellowship. Brogan had three brothers, of whom the best known was the conservative journalist
Colm Brogan (1902–1977). His other two siblings, Willie and Diarmuid, both taught at
St Mungo's Academy in the East End of Glasgow. == Career ==
