## Summary
Otto Jespersen was a Danish linguist (1860–1943) known for his foundational work in phonetics, syntax, and the historical development of negation in languages. He was a professor at the University of Copenhagen and Oxford, where he contributed to the International Phonetic Association and developed the Dania phonetic transcription system. His research on language evolution, particularly Jespersen's Cycle, remains influential in linguistics.
