Seán Mac Diarmada (MacDermott) (1883–1916), born near Kiltyclogher, Co. Leitrim, was the ‘master machinist’ of the Easter rising, who organised a vast underground network of insurrectionists by recruiting men into the secret Irish Republican Brotherhood and infiltrating them into the Irish Volunteers. Partially disabled by polio, and wearing civilian clothing, during Easter week he helped direct operations in the GPO, and was executed on 12 May 1916.
Seán Mac Diarmada's biography is taken from the book 1916 Portraits and Lives published by the Royal Irish Academy. 100 prints of the 42 portraits and 3 scenes from the book, signed and numbered by the artist David Rooney, are available to order while quantities last. The original portraits from the book have been acquired for the State Collection by the OPW and will be on exhibit in 2016 at Kilmainham Gaol, Dublin. Read more 1916 biographies.
