The first female president of the society was Irene Manton (1973 to 1976), who pioneered the biological use of electron microscopy. Her work revealed the structure of the flagellum and cilia, which are central to many systems of cellular motility. Present interests Recent years have seen an increased interest within the society in issues of biodiversity conservation. This was highlighted by the inception in 2015 of an annual award, the John Spedan Lewis Medal, specifically honouring persons making significant and innovative contributions to conservation. Locations The society has had a number of different homes, initially meeting in Marlborough Coffee House (1788), before moving to Panton Square in 1795, then Gerrard Street, Soho in 1805, and Soho Square in 1821.

Membership Fellowship requires nomination by at least one fellow, and election by a minimum of two-thirds of those electors voting. Fellows may employ the post-nominal letters 'FLS'. Fellowship is open to both professional scientists and to amateur naturalists who have shown active interest in natural history and allied disciplines. Having authored relevant publications is an advantage, but not a necessity, for election. Following election, new fellows must be formally admitted, in person at a meeting of the society, before they are able to vote in society elections. Admission takes the form of signing the membership book, and thereby agreeing to an obligation to abide by the statutes of the society. Following this the new fellow is taken by the hand by the president, who recites a formula of admission to the
