It was originally published in 1781/82 as "Die Entdekkung von Amerika - ein angenehmes und nützliches Lesebuch für Kinder und junge Leute" and deals with the discovery, early exploration and conquest of America by focusing on one explorer in each volume: Christopher Columbus is treated first, followed by Hernán Cortés and finally Francisco Pizarro.  The work is counted among the first books of specific children's literature, directly targeting children and adolescents as its main audience, and Campe said to have "set the standard for German children's literature."  The trilogy is defined by its author's involvement in the German educational movement of philanthropinism and has been a great success, also being translated into several languages.

Anna Essinger: Anna Essinger (15 September 1879 – 30 May 1960) was a German Jewish educator.  At the age of 20, she went to finish her education in the United States, where she encountered Quakers and was greatly influenced by their attitudes, adopting them for her own.  In 1919, she returned to Germany on a Quaker war relief mission and was asked by her sister, who had founded a children's home, to help establish a school with it.  She and her family founded a boarding school, the Landschulheim Herrlingen in 1926, with Anna Essinger as headmistress.  In 1933, with the Nazi threat looming and the permission of all the parents, she moved the school and its 66 children, mostly Jewish, to safety in England, re-establishing it as the Bunce Court School.  During the war, Essinger established a reception camp for 10,000 German children sent to England on the Kindertransports, taking some of them into the school.  After the war, her school took many child survivors of Nazi concentration camps. By the time Essinger closed Bunce Court in 1948, she had taught and cared for over 900 children, most of whom called her "Tante" ("Aunt") Anna, or TA, for short.  She remained in close contact with her former pupils for the rest of her life.
