1847–1924
A Victorian architect and architectural writer, he helped make the history of building styles more approachable for general readers. His best-known work was written with T. Roger Smith and offered a clear guide to classical and early Christian architecture.

by T. Roger (Thomas Roger) Smith, John Slater
John Slater was a British architect, born in Bishops Stortford in 1847. He studied at University College London and was articled to the architect and teacher T. Roger Smith, a connection that shaped both his professional work and his writing.
Alongside architectural practice, he is remembered as a co-author of Architecture, Classic and Early Christian, an illustrated handbook first published in the late nineteenth century. The book was designed as an accessible survey rather than a highly technical treatise, which helps explain why it has remained of interest to later readers.
Slater was also active in the profession’s institutions, serving as President of the Architectural Association and later as a Vice-President of the Royal Institute of British Architects. He died in 1924.
