Rosa (pronounced: zhay-nay RHAL zhock-mee-NOH), also called 'General Jack' or 'Jack Rose', is an early Hybrid Perpetual rose cultivar, developed by Roussel, an amateur from Meudon, and introduced by the gardener Rousselet in 1853. The flower was named in honor of Jean-François Jacqueminot (1787-1865), a French general of the Napoleonic Wars. Its parentage is unclear, but 'Gloire des Rosomanes' and 'Géant des Batailles' are considered probable ancestors.
Alexis Jacquemin (24 July 1938 – 14 August 2004) was a Belgian economist. He received his PhD at the Université de Liège, and became a professor at the University of Louvain (UCLouvain) in 1974. In 1983, he was awarded the Francqui Prize on Human Sciences.
Jeanne Jacqeumin (Marie-Jeanne Boyer) was a French artist associated with the Symbolist movement. She was born on 13 April 1863 in Paris and died in Paris in 1938. She married Édouard Jacquemin, but later left him to live with the engraver Auguste Lauzet, a friend of Vincent Van Gogh.
