The Memorial to Heroic Self-Sacrifice is a public monument in Postman's Park in the City of London, commemorating ordinary people who died saving the lives of others and who might otherwise have been forgotten. It was first proposed by painter and sculptor George Frederic Watts in 1887, to commemorate the Golden Jubilee of Queen Victoria. The scheme was not accepted at that time, and in 1898 Watts was approached by Henry Gamble, vicar of St Botolph's Aldersgate church. Postman's Park was built on the church's former churchyard, and the church was at that time trying to raise funds to secure its future; Gamble felt that Watts's proposed memorial would raise the profile of the park. The memorial was unveiled in an unfinished state in 1900, consisting of a 50-foot (15 m) wooden loggia designed by Ernest George, sheltering a wall with space for 120 ceramic memorial tiles to be designed and made by William De Morgan. At the time of opening, only four of the memorial tiles were in place. Watts died in 1904, and his widow Mary Watts took over the running of the project.
