The Society has been fortunate, over its history, to receive several significant donations and legacies – among these are those from Rayleigh, Larmor, Hardy and Fröhlich. They have been enormously valuable in enabling the Society to extend its support for mathematics and mathematicians.

How the Society supports mathematics

The London Mathematical Society (LMS), a registered UK Charity (no. 252660), is the UK’s learned society for mathematics. Its purpose is the advancement, dissemination and promotion of mathematical knowledge, both nationally and internationally. The LMS currently supports mathematics research in many ways.

The Society has an increasing number of calls on its funds and is keen to maintain and indeed increase its level of support for all of the above objectives. The long-term stability of these programmes depends on the Society having endowments, gifts and investments to support them.
