Seán O'Casey was an Irish dramatist and memoirist. A committed socialist, he was the first Irish playwright of note to write about the Dublin working classes.

Dorset Street is an important thoroughfare on the northside of Dublin, Ireland, and was originally part of the Slighe Midh-Luchra, Dublin's ancient road to the north that begins where the original bridging point at Church Street is today. Subsequently, yet prior to the street being given its current name in the 18th century, the road was known as Drumcondra Lane and was shown on maps as such. It is divided into Dorset Street Lower and Dorset Street Upper.
