[1] In 1857, Paul Rajon began to work for Pierre Joseph Meurisse, a photographer in Metz who had married his sister Marguerite, as a retoucher of portraits.
From 1859 to 1860 he attended an art course given by Auguste Migette at the school of design in Metz, befriending another student, Émile Boilvin [fr].
[1] A friend of Philippe Burty, Félix Bracquemond, and Louis-Charles-Auguste Steinheil, Rajon was awarded medals at the Paris Salons of 1869, 1870, and 1873, and at the Exposition Universelle of 1878.
He etched both contemporary works and Old Masters, as well as portraits, including ones of Ivan Turgenev, Théophile Gautier, John Stuart Mill, Charles Darwin, and Alfred, Lord Tennyson.
He was critically praised in France, Great Britain, and the United States, through his acquaintance with the New York-based American print dealer Frederick Keppel.
