Coronation Street is a British soap opera, initially produced by Granada Television. Created by writer Tony Warren, Coronation Street first broadcast on ITV on 9 December 1960. The following is a list of characters introduced in the show's fourth year, by order of first appearance. In April, outgoing series producer H.V. Kershaw saw the return of original cast member Philip Lowrie as Dennis Tanner after a year's absence. Kershaw vacated his position a month later, to be replaced by Margaret Morris — who in June secured a short return spot for David Barlow (Alan Rothwell), appearing in two episodes. Morris introduced two significant recurring characters in July, as (Geoffrey Matthews) and Walter Potts (Christopher Sandford) made their first appearances, while Myra Booth (Susan Jameson) became the only new regular character to be introduced in 1963 when she arrived in September. Myra's father George Dickenson (Stan Jay) followed her to Weatherfield in September, and Laurie Fraser (Stanley Meadows) began a five-month stint as a new love interest for Elsie Tanner in November. Jon Rollason also joined the cast as Dave Robbins in December.
