Arthur Horner (1894-1968) was a miners' leader from the 1926 general strike to his retirement as general secretary of the National Union of Mineworkers in 1959. During his life, he played a crucial role in the fight for a national mineworkers union, and in the development of the National Coal Board; he was a champion of the Republicans in Spain; he was imprisoned several times for his views; and, he was in constant demand as a speaker. But it was his warmth, good humour and enthusiasm which made 'little Arthur', as he was affectionately known by his union colleagues, really memorable.
