Ronnie Crapper and family were the first tenants of 9 Coronation Street after the house was built in 1902.

Ronnie's father Albert and brother Jack worked at the Weatherfield Main pit but mother Pearl was worried about Ronnie's weak chest and ensured he didn't follow suit. Instead, Ronnie got a job as an apprentice at Bright's Pawn Shop on the corner of Rosamund Street and Canal Street and it was this which saved him from being buried alive along with his father and brother in the pit cave-in in 1906.

In 1908, Ronnie got engaged to Rose Weaver, a housemaid in the employ of Charles Hardcastle. After they married in 1909, Rose moved into No.9 and a year later Ronnie took a job at Hardcastle's stables and the couple moved into a carriage house.

Ronnie first appeared in Daran Little and Bill Hill's "Weatherfield Life", published in 1992. Other information is derived from Little's follow-up book, "Around the Coronation Street Houses".
