Kenneth Mathiason Skeaping (13 December 1856 – 16 May 1946) was an English lithographer, portrait painter and illustrator. His three children who survived to adulthood became leading exponents in early music, sculpture, and ballet.

Skeaping was born in Liverpool on 13 December 1856 to decorative wood carver Joseph Nairn Skeaping (baptised on 6 August 1829 – 1 January 1902) and Mary Pollock Mathiason (baptised on 24 May 1835 – 14 March 1917), who had married at St. Philip's Church, Liverpool on 10 April 1853.

Skeaping was the second of the couple's nine children, and the eldest boy. At least two of his siblings had careers in the arts. His brother John Skeaping (21 May 1859 – 4 May 1940) was a figure and landscape painter, and a lithographer. His sister Elizabeth Jane "Lily" Skeaping (14 September 1870 – 31 October 1947 ) was a figure, landscape, and miniature painter.

It is not clear where Skeaping was educated. His family were close knit, and he initially worked with his mother helping her to make wigs from real hair, before training as a lithographic artist, which is how he recorded his occupation in the 1881 census. He was still registered to vote at his parents' home at 50 Warren StreetHe travelled to London in the early 1880s and met his future wife there in 1886. He subsequently spent time in Paris adsorbing the art of the impressionists and post-impressionists.

In 1895 he married Sarah Ann Rattenbury (2 January 1867 – second quarter 1960), the daughter of the late Thomas Swaine Rattenbury (6 June 1830 – 22 June 1877), a grocer and cheeses monger of New Cross. and grocer's shopwoman Sarah Rattenbury née Day (c. 1832 – 10 October 1898). The couple had four children:

The children had an unusual upbringing, apparently being educated entirely at home until their teens. In an interview in 1968, his son John recalls Skeaping as saying: ". . . two great qualities that children have are imagination and the power of imitation so the only things they should do is develop their imagination by learning music, dancing, painting, sculpture, and so forth an imitation - they can learn languages. What is stuffed into children against their will over ten years they can forget in six months. What you learn willingly over that ten years, you never forget."

The eldest child was born in Woodford in Essex in 1897, and their address at the baptism of Sally in December 1899 was Kersal Villa, Malmsbury Road, South Woodford, Essex. They were still there in 1905, but by the time of the 1911 census they were living at Cliftonville, Warren Road, Bexleyheath, London, and were still there in 1918. by 1929 the electoral register shows the family had moved to 2 Eton College Road, in Camden, London. They were still there ten years later at the time of the 1939 Register in September of that year, and in the street directory for 1840. However, Skeaping had moved to Corners, Cross Road, Tadworth in Surrey by 1945, and was said to have lived there for several years when he died in 1946.

Skeaping died on 16 May 1946. He was 89 years old. His wife survived him by fourteen years, dying at the age of 93.
