Joseph Stretch Crowther (1820âÂÂ1893), usually known as J. S. Crowther, was an English architect who practised in Manchester.
Crowther studied under Richard Tattersall from 1838 to 1843. He then worked as a managing clerk for Henry Bowman until 1846, when Bowman took him into partnership; the firm was known as Bowman and Crowther.
Crowther subsequently established an independent practice, designing churches in the Gothic Revival style and villas in a variety of other styles. He was appointed diocesan architect for Manchester Cathedral and was working on its restoration at the time of his death in March 1893.
