This book describes the astonishing achievements of John Angus Mackay - a man whose intelligence, humanity, political nous, people skills, wit, steely resolve and courage, were such that, what lesser beings regarded as impossible, he made possible. Through his efforts in concert with a small group of others, a thousand year process of 'ethnic cleansing' of the Gaelic language and culture was challenged and new means created to rebuild that which the powers-that-be had long sought to destroy. These efforts were so successful that now, the Scottish Gaelic language and culture has turned the corner and the number of young Gaelic speakers is increasing. How this was achieved, against a sustained barrage of negativity, is described, but perhaps his most obvious achievement is his long, dogged and forensically focused campaign, against huge establishment resistance, to win a Gaelic television channel. That channel now provides a fascinating range of programming at times attracting viewership figures well in excess of the total number of Gaelic speakers in Scotland. But that is only part of the story. John Angus was also a gifted teacher, pivotal in developing community co-operatives in his native Lewis, in paving the way for the creation of the Crofters' Union and leading the development of the Gaelic Comunn na Gàidhlig, Bòrd na Gàidhlig, An Lanntair multi-arts venue, the University of the Highlands and Islands, and as its chairman, in turning round NHS Western Isles from crisis into a model small health board.
