Chemical Physical Society
In 1876, the Chemical and Physical Society was established, with Oliver Lodge as the first President. In that first year there were 41 paying members and 7 honorary members; it held 17 meetings, with an average attendance of 15. It is of course still going strong, and can claim to be the oldest student scientific society in England.
