He moved to Edinburgh in 1894 as Head of French at the University of Edinburgh (as Dr Sarolea). He initially lived in a flat at 74 Bruntsfield Place. In 1903 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were George Chrystal, Alexander Crum Brown, Sir Francis Grant Ogilvie and James Gordon MacGregor.
In 1915, he was sent by the Belgian government to the United States in order to support the veracity of atrocity stories in circulation about the German occupation of Belgium. The mission was not a success, in that Sarolea unwisely and publicly attacked the neutrality that the US was observing at the time with respect to World War I. Recent academic interest has been on his political views.
In 1918 he was given his professorship by the University of Edinburgh which he held until retiral in 1931.
He died in Edinburgh on 11 March 1953.
He married twice: firstly in 1895 to Martha van Cauwenberghe, then secondly in 1905 to Julia Dorman.
His daughter Marie Antoinette Sarolea married Ian Bartholomew.
