The joint LSE/QM colloquia began as a series of annual combinatorics meetings at the University of Reading in 1970.
The meetings were were originally organised by David Daykin and subsequently by Anthony Hilton and Crispin Nash-Williams.
This series evolved into two paired one-day colloquia on consecutive days in May at the LSE and Queen Mary, when Anthony Hilton moved to Queen Mary. The first LSE/QM colloquia took place in 2007 and were jointly organised by Anthony Hilton and Robert Johnson at Queen Mary and Graham Brightwell at LSE.
