The Liverpool Royal Infirmary School of Medicine Debating Society (MSDS) was founded in 1874^[3] by Dr. Richard Caton.^[4] The society was formed seven years ahead of the University of Liverpool.^[5] The original society was a male-only entity, and often debated such things as whether females should be admitted into the medical school. In 1885 it became the University College Medical School Debating Society, then 1902 a further change of name to the Liverpool University Medical School Debating Society. The society finally decided to admit female medical students in 1905, and the first female doctor to graduate from Liverpool was Phoebe Powell in 1910.The society began publishing a magazine "the Sphincter" in 1937 a play on the university student magazine the Sphinx ^[6] In 1943 the society changed their name to the "Liverpool Medical Students Society", wanting to being recognised for more than debating.^[4] The society is the longest-running students society at the university.

The Society records the names of its Student Officers and Honorary Presidents in the Jack Leggate Theatre of the Victoria Gallery & Museum. Previous Honorary Presidents of the Society have included Henry Cohen, 1st Baron Cohen of Birkenhead, Professor Sir Ian Gilmore, Professor Sir Cyril A. Clarke KBE, and Professor Thomas Cecil Gray CBE KCSG. It's plaque reads:

"Established as Royal Liverpool Infirmary School of Medicine Debating Society in 1874 by Dr. Richard Caton, Making this the oldest society of its kind in the country. Continued as University College Medical School Debating Society from 1885, Becoming Liverpool University Medical School Debating Society in 1902. It was finally transformed to Liverpool Medical Students Society in 1943."

The Society is registered as a charity in England and Wales.^[7] The board consists of 14 members,^[8] of whom most are senior practicing Medical Practitioners and eminent Alumni.^[9] The Society is run primarily by three officers, the President, Treasurer and Secretary. A full committee of 39 medical students is elected at the AGM. They cover a portfolio of areas including entertainment & socials, charities, welfare, clubs & societies and the Annual Medical Ball.

More recently, the Society has gathered national media attention for its "Jack Leggate" song and its infamous Annual Smoking concert which started in the 1880s.^[1][4]

On 10 November 2014 the online feminist magazine The Vagenda tweeted a screenshot which apparently showed a proposed script for the Annual Smoking Concert which had been circulated among fourth year medical students.^[10] The explicit content sparked claims that students responsible were misogynistic and that the concert itself was contributing to a "Lad culture" at the university.^[11] The Mirror Online highlighted the explicit lyrics of the LMSS's "Jack Leggate song", stating;

"The society is also known for singing an explicit song at society events which includes the line “we like those girls who say they won't but look as though they might”"^[12]

The university and Liverpool Guild of Students subsequently released a statement condemning the content and promising an internal inquiry into the materials for the production.^[13]

On 14 January 2016 Liverpool Guild of Students officially de-ratified the society barring its use of guild services.^[14]

On 15 January 2016, a petition was created on change.org opposing the de-ratification of the LMSS, which demanded the immediate resignation of Liverpool Guild of Students President Harry Anderson.^[15] The petition gained over 1,200 signatures in 3 days.^[16] .^[17] The society maintains its commitment to change its perceived culture of exclusivity with a revamped agenda on cultural diversity and inclusion and build on its longstanding tradition of charity work.^[18]

On 5 February 2019, it was announced that the LMSS was fully re-integrating with the University of Liverpool.^[19]
