Rackham was born in London as one of 12 children. At the age of 18, he worked as a clerk at the Westminster Fire Office and began studying part-time at theLambeth School of Art.
In 1892 he quit his job and started working for The Westminster Budget as a reporter and illustrator. His first book illustrations were published in 1893 in To the Other Side by Thomas Rhodes, but his first serious commission was in 1894 for The Dolly Dialogues, the collected sketches of Anthony Hope, who later went on to write The Prisoner of Zenda. Book illustrating then became Rackham's career for the rest of his life.In 1903 he married Edyth Starkie, with whom he had one daughter, Barbara, in 1908. Rackham won a gold medal at the Milan International Exhibition in 1906 and another one at the Barcelona International Exposition in 1912. His works were included in numerous exhibitions, including one at the Louvre in Paris in 1914. Arthur Rackham died 1939 of cancer in his home in Limpsfield, Surrey.
Rackham invented his own unique technique which resembled photographic reproduction; he would first sketch an outline of his drawing, then lightly block in shapes and details. Afterwards he would add lines in pen and India ink, removing the pencil traces after it had dried. With color pictures, he would then apply multiple washes of color until transparent tints were created. He would also go on to expand the use of silhouette cuts in illustration work.
