Reprint of the original, first published in 1885.

Biographies of more than 100 Irish scientists (or those with strong Irish connections), in the disciplines of Chemistry and Physics, including Astronomy, Mathematics etc., describing them in their Irish and international scientific, social, educational and political context. Written in an attractive informal style for the hypothetical 'educated layman' who does not need to have studied science. Well received in Irish and international reviews.

Volume IV: The Irish Book in English 1800-1891 details the story of the book in Ireland during the nineteenth century, when Ireland was integrated into the United Kingdom. The chapters in this volume explore book production and distribution and the differing of ways in which publishing existed in Dublin, Belfast, and the provinces.
