Catherine Charlotte Raper (1766–1809) was an English pastellist.
Raper was almost certainly the daughter of Henry and Catherine Raper who was baptized in the church of St Andrew Holborn. In 1789, she received the Greater Silver Pallet Award from the Society of Arts for one of her pastels. Later that year, in Calcutta, she married a colonel in the service of the East India Company, James Edward Brown. Five years later, still in that city, she married again, this time to Lieutenant Charles Fraser. The couple had ten children, three of whom were born after the couple returned to London. Raper died in Lewisham.[1]
