First published in 1866, this book caused a sensation in Europe and America, sparking a wave of recreational canoeing by such well-known figures as Robert Louis Stevenson and inspiring paddlers from the Victorians to the modern practitioners of canoe camping and sea kayaking.
Originally a patent lawyer, MacGregor generally ignored the practice after 1853 and devoted his life to travel and philanthropy. In addition to A Thousand Miles, he also wrote three other popular voyaging books: A Voyage alone in the Yawl Rob Roy (1867); The Rob Ray on the Baltic (1867); and The Rob Roy on the Jordan, Red Sea, and Gennesareth (1869). For each trip, MacGregor had a new decked canoe built which retained its predecessor's title.
A Thousand Miles in the Rob Roy Canoe is generally considered to have been one of the most popular books of 1866--in modern parlance: the year's top nonfiction bestseller. The novelty of MacGregor's mode of travel in 1865 generated newspaper coverage not only across Europe but also as far away as the United States, Canada, and South America. In many ways, this trip was one of the first "media events" ever recorded across continents.
MacGregor is generally recognized as the prime inspiration for the growth of canoeing, canoe camping, and canoeing clubs in Europe and America (he was also the founder of the Royal Canoe Club which was "commodored" by the Prince of Wales), and by extension, the father of modern sea kayaking. In fact, the several versions of the Rob Roy were "decked" canoes, or in modern terms, a hard-shell sea kayak.
