I recently paid a visit to the University College London Hospital (UCLH) archives in Euston to discuss gratitude and see some of the archive’s holdings. Annie Lindsay and Penny McMahon have charge of a vast amount of material. Some fascinating highlights are on public display in UCLH’s highly recommended heritage trail. Annie and Penny gave me an insight into the kinds of documents that are preserved. Patronage, of course, is well documented, and this has an enduring legacy in a number of wards in hospitals being named for their donors. Complaints are also kept on record although, interestingly, Annie pointed out that in the past this largely depended on the diligence of the superintendent in charge.
