Robert Lloyd Praeger (25 August 1865 – 5 May 1953) was an Irish naturalist, writer and librarian.
From a Unitarian background, he was born and raised in Holywood, County Down. He attended the school of the Reverend McAlister and then the nearby Sullivan Upper School.
He worked in the National Library of Ireland in Dublin from 1893 to 1923. He co-founded and edited the Irish Naturalist , and wrote papers on the flora and other aspects of the natural history of Ireland. He organised the Lambay Survey in 1905/06 and, from 1909 to 1915, the wider Clare Island Survey. He was an engineer by qualification, a librarian by profession and a naturalist by inclination.
He was awarded the Veitch Memorial Medal of the Royal Horticultural Society in 1921. He became the first President of both An Taisce and the Irish Mountaineering Clubin 1948, and served as President of the Royal Irish Academy for 1931–34.
He is buried in Deansgrange Cemetery, Dublin, together with his wife Hedwig. His younger sister Rosamond Praeger was a sculptor and botanical artist.
Praeger was instrumental in developing advanced methodologies in Irish botany by inviting Knud Jessen, the acclaimed Danish expert in Glacial and Post-Glacial flora, to undertake research and teaching in Ireland. This was to lead to the establishment of 'paleoecology' as a distinct field of study in Ireland.
A vice-county system was adopted by Praeger dividing Ireland into forty vice-counties based on the counties. However the boundaries between them does not always correspond to the administrative boundaries and there are doubts as to the correct interpretation of them.
