Gail Jefferson

Gail Jefferson (22 April 1938 – 21 February 2008) was an American sociologist with an emphasis in sociolinguistics. She was, along with Harvey Sacks and Emanuel Schegloff, one of the founders of the area of research known as conversation analysis (CA). She is remembered for the methods and notational conventions she developed for transcribing speech, the latter forming the Jefferson Transcription System. This is now used widely in CA research.
