Wolfgang Iser (22 July 1926 – 24 January 2007) was a German literary scholar.
Wolfgang Iser was born in Marienberg, Germany. His parents were Paul and Else (Steinbach) Iser. He studied literature in the universities of Leipzig and Tübingen before receiving his PhD in English at Heidelberg with a dissertation on the world view of Henry Fielding (1950). A year later, Iser was appointed as an instructor at Heidelberg and in 1952 as an assistant lecturer at the University of Glasgow. There, Iser began to explore contemporary philosophy and literature, which deepened his interest in inter-cultural exchange. He subsequently lectured in many other parts of the world, including Asia and Israel. He was married to Lore Iser.
Iser is known for his reader-response criticism in literary theory. This theory began to evolve in 1967, while he was working in the University of Konstanz, which he helped to found in the 1960s. Together with Hans Robert Jauss, he is considered to be the founder of the Constance School of reception aesthetics. In his approach to reader-response theory, Iser describes the process of first reading, the subsequent development of the text into a 'whole', and how the dialogue between the reader and text takes place. In his study of Shakespeare's histories, in particular Richard II, Iser interprets Richard's continually changing legal policy as expression of the desire for self-assertion. Here he follows Hans Blumenberg, and attempts to apply his theory of modernity to Shakespeare. In this theory of modernity is self-assertion, which responds to the destruction of scholastic rationalism in the nominalist revolution (with William of Ockham).
