Norman Macleod Ferrers (11 August 1829 – 31 January 1903) was a British mathematician and university administrator and editor of a mathematical journal.From 1855 to 1891, he worked with J. J. Sylvester as editors, with others, in publishing The Quarterly Journal of Pure and Applied Mathematics.[3] One of his early contributions was on Sylvester's development of Poinsot's representation of the motion of a rigid body about a fixed point.In 1881, he studied Kelvin's investigation of the law of distribution of electricity in equilibrium on an uninfluenced spherical bowl and made the addition of finding the potential at any point of space in zonal harmonics.[7] On 3 April 1866, he married Emily, daughter of John Lamb, dean of Bristol cathedral.
