The family lived at Grade II* Amcott House, Grove Street, Retford (now the site of Bassetlaw Museum).
Stephen retired from business in 1907 and continued living with his mother and sister after his father's death.
Stephen Pegler was a successful industrialist but is best known for his autochromes, a form of early colour photograph.
They show everyday life in and around Retford including picnics, processions, outings, sports, gardens, interiors, shop windows, the markets, events at the Town Hall, farms and celebrations of national events.
It has been assembled from various sources, including a house in Bolham Lane, which had been bought by Pegler for his retired housekeeper.
