reissued a classic text on Fossil Plants which features at least one illustration by Thomas. Henry Matthew (18751960) Henry Matthew "Harry" Brock was born on Sunday, 11 July 1875. He was the most prolific illustrator of the Brocks, and one of the most prolific illustrators of his generation. He was the longest living of the Brock brothers, dying at the age of 85. Of his siblings, only Katharine, who lived to 91, was longer living. Kelly includes in the plates in his book a photograph of Henry working away at his easel at 78 years of age. Like his siblings he was educated first at St. Barnabas, and like his brothers he also attended the Higher Grade Boys' School. Here he was a regular prize winner. When he attended the Cambridge School of Art, he was repeatedly awarded a free studentship by the Science and Art Department at South Kensington. His first book illustration appears to have been a collaborative effort with Charles for a history reader by Macmillan. This was followed by 40 illustrations for Frederick Marryat's Japhet in Search of a father (Macmillan, London. 1885). From then on he was illustrating books and magazines almost up until his death. Henry married Doris Joan Pegram (12 June 18861 November 1979 at St. Paul's in Hampstead on 7 September 1912. Doris was the eldest daughter of the Henry's cousin, sculptor Henry Alfred Pegram and Alice Lambert (born 13 January 1865), described as an artist's model in the 1881 census. Both Houfe and Kirkpatrick state that Doris was the sister of illustrator Fred Pegram. but close examination of the census returns show that Thomas Weely Pegram was Richard's maternal grandfather, Fred's paternal grandfather, and Doris's paternal great-grandfather.</ref> Therefore Doris was a daughter of Fred's first cousin, and Henry was Fred's first cousin. The couple lived at a house that Henry had designed at "Woodstock", 63 Storey's Way, in Cambridge. After the Second World War, the couple move back to Arundine House, which had now been divided into three apartments. They lived in Flat 2 and Flat 3 with their two daughters. The couple had three children: Margaret Marion Brock (12 November 19133 January 1967) She attended the Perse School for Girls in Cambridge. Marion was heavily involved with the Women's Institute in Cambridge. Marion never married and she was still living in one of the Arundine house flats when she died
