Herman "Jackrabbit" Smith-Johannsen,  (June 15, 1875 – January 5, 1987) was a Norwegian supercentenarian, credited for introducing cross-country skiing to Canada and North America. In his youth he was rated one of the best all-round Norwegian skiers.
Johannsen was born in Horten, Norway, the oldest of nine children. After studying in Berlin he moved to the United States before settling in Piedmont, Quebec. He married Alice Robinson (born 1882) in 1907. They had three children; Alice (1911–1992), Robert "Bob" (1915–2001) and Peggy (1918–2014).
The family moved to Pelham just outside New York City in 1916. Johannsen managed a business importing heavy-equipment from Norway to North America and Cuba, shuttling between New York and Montreal, until the family permanently settled in Canada ca. 1929.
Johannsen died from pneumonia on January 5, 1987 at the age of 111 years, 204 days, near Tønsberg, Norway, being the oldest man in the world for the last 22 days of his life. He is buried by the St. Sauveur church in Saint-Sauveur, Quebec, Canada, next to his wife, who died in 1963. His archives are held at the McGill University Archives in Montreal.
Johannsen graduated from the Norwegian Military Academy in 1894 with a commission as a lieutenant in the Norwegian Army Reserve. In 1899 he graduated with an engineering degree from the University of Berlin. Two years later he moved to Cleveland, Ohio where he worked at selling heavy machinery. In 1907 he became an independent agent, selling heavy equipment, based out of New York City and eventually Montreal.
Johannsen is credited with building many ski jumps and with blazing trails throughout Ontario, the Eastern Townships, the Laurentians, and the Adirondack Mountains in New York. In 1972 he was appointed as a Member of the Order of Canada for fostering and developing skiing as a recreation and helping and encouraging generations of skiers in Canada.
Founded in 1986, the Jackrabbit Ski Trail in the Adirondacks is a long-distance cross-country ski trail that links the populated areas of Keene, Lake Placid, Saranac Lake and Paul Smiths with developed cross-country ski centers and some longer sections of wilderness skiing to make possible a tremendous variety of ski trips. The trail is approximately 50 kilometers, or, 31 miles.
The trail is named in honor of Johannsen. While living and vacationing in Lake Placid between 1916 and 1928, Johannsen laid out some of the original routes used by today’s trail. He was also famous for his one-day ascents of Mount Marcy (the highest mountain in New York State at 5,344 feet above sea level) starting from Lake Placid- a round-trip of over 30 miles.
Johannsen is also the namesake of Cross Country Canada's Jackrabbit program designed to introduce children 6-9 to cross-country skiing through local ski clubs. Some former "Jackrabbits" introduced to skiing through the program include Olympic medalists Beckie Scott, Sara Renner, and Chandra Crawford and World Champions Devon Kershaw and Alex Harvey.
