Stoneley, Robert (14 May 1894–2 February 1976; elected F.R.S. 1935), was born at 102 Mayola Road, Clapton, London E.5, on 14 May 1894. His father, also Robert, was a builder, and his mother was Fanny, née Bradley. He had one younger brother, Maurice. The house was close to where the railway crosses the River Lea. He married (28 March 1927) Dorothy Minn, whom he had known since childhood; her parents were Gayford Duge Minn and Annie, née Okey, sister of Thomas Okey, sometime Professor of Italian at Cambridge. There are two sons, Robert and Anthony John Martin, born 1929 and 1944; a daughter, Ruth Margaret, who was born in 1931 died in 1940. Both sons are members of Pembroke College and Ph.D.’s of the University of Cambridge. Robert is a geologist with the British Petroleum Company, and Anthony a computer officer at the Cambridge University Computer Laboratory.
Stoneley was at Parmiter’s School 1904–10, then at the City of London School, 1910–12, where he got the Mortimer Exhibition for Science and medals for arithmetic and chemistry and also a Leaving Exhibition awarded by the Worshipful Company of Broderers in 1912.
He entered St John’s College, Cambridge, in 1912 with a £40 Foundation Scholarship in Natural Sciences. He obtained first classes in Part I of the Mathematical Tripos in 1913, Natural Sciences Part I in 1914 and Mathematics Part II with distinction in Schedule B in 1916. He took his B.A. in 1915 and M.A. in 1920, and was awarded the

Classics of Elastic Wave Theory
In this chapter, we give a brief synopsis of each of the classic papers referred to in this collection. Where relevant, we reproduce the basic equations, recast in modern notation. Supporting works also are referred to. They are listed in the “General References” section.
Table 1 is a quick outline of the key contributions of each paper reprinted in this book.
Robert Hooke, “Potentia Restitutiva, or Spring” (Oxford, 1678)
The article by Robert Hooke, “Potentia Restitutiva, or Spring,” contains the statement of the proportional relation between stress and strain universally referred to as Hooke’s law. Although the English language has evolved somewhat since 1678, the article does not require translation. Hooke describes a variety of experiments, accompanied by illustrations, confirming the stress/strain relation over a wide range of applied loads. He emphasizes the great generality of his results.
Based on his experimental work from 1660 onward, Hooke first published his law in 1676 in the form of an anagram in Latin,
which he later revealed to be “ut tensio sic vis.” Roughly translated, this means “as the force, so is the displacement” (Love, 1911; Boyce and DiPrima, 1976).
In his treatise, Hooke examined the behavior of springs, so his first casting of the equations dealt with the restoring force on a spring, for a given displacement:
