In 1845 Howson, having taken orders, accepted the post of senior classical master at the Liverpool College under his friend W. J. Conybeare, whom he succeeded as principal in 1849. This post he held until 1865,[1] and it was largely due to his influence that a similar college for girls was established at Liverpool.
His sympathies were with the evangelical party, and he stoutly opposed the "Eastward position," but he was by no means narrow. He did much to reintroduce the ministry of women as deaconesses. The building of the King's School for boys, and the Queen's School for girls (both in Chester), was due in a great measure to the active interest which he took in educational matters.
Howson's chief literary production was The Life and Epistles of St Paul (1852) in which he collaborated with Conybeare.
Family
He married the daughter of John Cropper, who survived him by only a few days.[5] He died at Bournemouth on 15 December 1885 and was buried in the cloister garth of Chester.
