The Victoria Institute, or Philosophical Society of Great Britain, was founded in 1865, as a response to the publication of On the Origin of Species and Essays and Reviews. Its stated objective was to defend "the great truths revealed in Holy Scripture ... against the opposition of Science falsely so called." Although it was not officially opposed to evolution, it attracted a number of scientists sceptical of Darwinism, including John William Dawson and Arnold Guyot.

Sir George Gabriel Stokes, 1st Baronet, was an Irish physicist and mathematician. Born in County Sligo, Ireland, Stokes spent all of his career at the University of Cambridge, where he was the Lucasian Professor of Mathematics from 1849 until his death in 1903. As a physicist, Stokes made seminal contributions to fluid mechanics, including the Navier–Stokes equations; and to physical optics, with notable works on polarization and fluorescence. As a mathematician, he popularised "Stokes' theorem" in vector calculus and contributed to the theory of asymptotic expansions. Stokes, along with Felix Hoppe-Seyler, first demonstrated the oxygen transport function of haemoglobin, and showed colour changes produced by the aeration of haemoglobin solutions.
