Leiva Konstanze Petersen was born in Berlin. Her father, Carl Petersen was originally from :dk:Hviding Sogn|Hviding in Northwest Schleswig. Carl Petersen was a history professor at Kiel till 1939 when he switched to Greifswald. Leiva Petersen's mother, born Ida Minna Räuber, was a teacher. A cousin was Günther Ramin, the organist and director of music at St. Thomas Church, Leipzig. She attended school at Marburg and Kiel, and then studied Classical Philology, History and Archeology successively at Frankfurt, Munich, Kiel and Würzburg. It was at Munich that she first met :de:Uvo Hölscher |Uvo Hölscher, a fellow student of philology who became a lifelong friend. In 1937 she received her doctorate, supervised by Karl Reinhardt from Frankfurt for a piece of work on the "... history of personification in Geek poetry and visual art". After this she undertook an extended study trip to Italy, also taking time to work for a time as a home tutor in Denmark. Back in Germany, in 1939 she passed the exams necessary to take up a teaching career in higher education. Now, however, she embarked on a book trade apprenticeship with Hermann Böhlaus Nachfolger, a venerable publishing institution that could trace its convoluted and at times illustrious history back to the "Weimarer Hofbuchdruckerei" founded in 1624. Just three years later, in 1942, she found herself in charge of the business, known as its "Kommanditistin". She retained the responsibilities which the appointment involved till her career ended in 1983. War, which had broken out in 1939, ended in May 1945, with a large part of what had been central Germany - including Weimar - administered as the Soviet occupation zone. In 1946 Petersen obtained one of the first private company licences from the Soviet military administrators, in 1947 becoming personally responsible for the business. Under her leadership the business produced academic editions of German classics and Reformation literature, including the works of Goethe, Schiller and Luther, along with the humanities more generally. From 1951/52 she also embarked on a parallel part-time career as a freelance co-author. Meanwhile the Böhlau company continued for several decades to be one of the last independent publishing businesses inside what had become, in October 1949, the Soviet sponsoredGerman Democratic Republic. In 1978 the business was sold to the German Academy of Sciences and Humanities: Petersen continued to run it, now as a department of the academy, till 1983. Alongside her responsibilities in publishing, between 1961 and 1972 Petersen held a part time appointment as a Classical Philosopher and Senior Assistant at the Academy of Sciences and Humanities. Successful projects included producing an updated and enlarged edition of the Prosopographia Imperii Romani, a lexicon of Roman empire state officials. As she grew in eminence she also sat as a member of various important committees. She was a member of the Administration Committee for the Schiller National Exhibition and the committee of the :de:Deutsche Schillergesellschaft| German Schiller Society. She was on the board of the Shakespeare Society and a member of the Publishers' Committee with the :de:Börsenverein des Deutschen Buchhandels|German Book Exchange. Having retired from regular employment in 1983, Leiva Petersen died at Weimar, where she still lived, on 17 April 1992.
