A plaque has been put up at the former home of a man who campaigned against the slave trade.
Some of Samuel Bowly's distant relatives were in Gloucester to witness the unveiling.
The unveiling coincides with anti-slavery day.
Bowly was a Quaker and although slavery had been outlawed by 1840 when he took part in the world anti-slavery convention, he campaigned hard against slavery in the rest of the world.
He also campaigned for temperance. He signed a pledge of total abstinence from drink in 1835 and worked to expose the dangers of alcohol all his life.
His great great grandson Anthony Barlow says his achievements were immense.
Bowly died in Gloucester in 1884 and at his funeral the Gloucester Cathedral bells tolled.
Now his name on the house he once lived in is a permanent reminder of his achievements.
