The **London Mathematical Society** dates back to 1864.

Augustus De Morgan's wife, writing after his death described how the London Mathematical Society was founded:-

It was in the year1864that Mr Arthur Cowper Ranyard and George[George De Morgan, Augustus De Morgan's son]were discussing mathematical problems during a walk in the streets, when it struck them that it would be very nice to have a Society to which discoveries in mathematics could be brought, and where things could be discussed like the Astronomical. It was agreed between the young men that this should be proposed and that George should ask his father to take the chair at the first meeting.

At a preliminary meeting to discuss setting up the Society on 7 November 1864, the name 'London Mathematical Society' was chosen. This was not the first name which had been proposed which was 'London University Mathematics Society'. De Morgan first proposed that the name be 'University College Mathematics Society' but then, feeling that aiming at a wider membership would be sensible, he proposed 'London Mathematical Society'. In fact this November 1864 meeting was meant to be the first proper meeting of the Society but De Morgan was ill and could not attend. The chair at this preliminary meeting was taken by T A Hirst, the name of the Society was agreed, and the date for the first meeting proper was set for 16 January 1865.

At the 16 January 1865 meeting, held in University College, Bloomsbury, north of central London, the chair was taken by Augustus De Morgan who gave the first address setting out what the aims and practices of the Society should be. This meeting was attended by 27 mathematicians who were joined as members by a further 43 during the first year of the Society. Cayley, Clifford, De Morgan, Hirst, Maxwell, Salmon, Smith, Spottiswoode and Sylvester had all joined by the end of 1865. The first six Presidents of the Society are among the nine mathematicians we have just listed. It is worth noting that, except for De Morgan, who refused a Fellowship of the Royal Society, all presidents of the London Mathematical Society have been Fellows of the Royal Society of London.

The Society rapidly expanded and moved away from its initial base in University College. Within two years of the founding of the Society it had moved into Burlington House, Piccadilly, occupying a room in the premises of the Royal Astronomical Society. There was, of course, already a connection with the Royal Astronomical Society since that Society had earlier absorbed the Spitalfields Mathematical Society. The Society rapidly gained international status, and two years after it was founded, in 1867, it instituted a category of honorary foreign member. The first such member was Chasles.

From its foundation the Society decided that it would publish a journal, the *Proceedings of the London Mathematical Society.* Between the first meeting in January 1865 up to November 1866, 37 papers had been presented. However the membership had rapidly increased and the cost of distributing the Proceeding to the members would have been too expensive if all the papers had been published. To keep down costs only eleven of the 37 papers were published. Financial pressures continued on the young Society, largely caused by the high volume of papers it was receiving. Only a donation of £1000 by Rayleigh in 1874 allowed the Society to become financially secure. The quantity and quality of papers published in the Proceeding was impressive, over 900 papers appearing by 1900.

The London Mathematical Society established prestigious prizes early in its existence. Once the finances allowed, the Society began the award of its De Morgan Medal. It was awarded once every three years, the first award being made to Cayley in 1884. The next recipients were Sylvester (1887), Rayleigh (1890), Klein (1893), Roberts (1896), and Burnside (1899).

One of the most influential members of the Society was G H Hardy. He was President in 1926-28 and again in 1939-41. He pressed for the Society to expand its range of mathematical publications and in 1926 the *Journal of the London Mathematical Society* was founded. The *Proceedings* published longer papers, the *Journal* took the shorter notes. The Society further expanded its list of journals in 1969 when the *Bulletin of the London Mathematical Society* began publication. Most recently, in 1997, the electronic journal the *London Mathematical Society Journal of Computation and Mathematics* was set up.

In the same year the this electronic journal was set up the Society decided that it needed premises of its own if it were to further expand its activities. The Society moved into a building in Russell Square in 1998, which was named *De Morgan House*.
