Keith Edward Kissack MBE (18 November 1913 – 31 March 2010) was a British schoolteacher and historian. He is notable for his many publications on the history of Monmouth and Monmouthshire.

Kissack was born in Clun, Shropshire, to Rev. Bernard Kebble Kissack and Caroline Keith-Murray. His mother was a descendant of the Murray of Blackbarony family of Scotland, Edmund Murray Dodd, a leading figure in Nova Scotia in the mid 19th Century, and David Mathews, the Mayor of New York City under the British during the American Revolution.

Kissack attended Durham School where he was a member of the school cricket team in 1931 and 1932. He later attended St Mark and St John's College, Chelsea, where he trained as a teacher.^[1]

He married Audrey Winifred Jones, of Monmouth in 1939, and daughter Bethia was born in 1940. He achieved the rank of captain in the Second World War, serving in North Africa, Sicily and Italy, where he was wounded.

After the Second World War, his second daughter Hermione was born in 1946. Kissack taught in Monmouth, becoming headmaster of Priory Street School. He served on Monmouth Town Council, and was a magistrate who chaired the local bench. He was also Curator of the Monmouth Museum, worked with the Royal Monmouthshire Royal Engineers to create their museum at Castle House, and a Fellow of the Society of Antiquaries.^[2][3] He was made MBE in 1976.^[4] In the Preface to the third volume of the Gwent County History, published the year before Kissack's death, the General Editor Ralph A.
