Guy Haworth: "His father was a Professor of Mathematics (hence the 'Professor' above) and wrote a book on Integration solutions - my school had a copy (with hard, orange covers)."

The man was Reginald Walter Kenrick (RWK) Edwards (born 1862), educated at Cambridge and taught at King's College, London. He authored The Mermaid of Inish-Uig (1898), Dick Vaughan's First Term (1901), A Radial Area-Scale (1904), and An Elementary Text-Book of Trigonometry (1911). I can't find the Integration book to which you refer but I'll note that Sir Alfred Lodge authored Integral Calculus for Beginners (1905) about which is written (The Mathematical Gazette): "The most novel feature of the book is perhaps the seventh chapter dealing with approximate methods of integration. Here, after the well-known rules of Simpson and Weddle, approximate formulae, recently devised by Mr. R. W. K. Edwards and Professor Lodge himself, are given, for dealing with the case in which the curvilinear boundary of a required area cuts the axis at right angles; a case for which, as is well known, rules of the Simpson type are not well fitted."
