Why you might have heard of Sir Thomas Pierson Frank

“The man who saved London from drowning”, Sir Thomas Peirson Frank, was a civil engineer and surveyor best known for protecting the city from floods during World War II.

When bombing raids breached the flood walls along the River Thames, Sir Thomas organised rapid-response teams to repair them and prevent major flooding.

The ICE’S 82nd President from 1945-1946, throughout his career Sir Thomas worked on flood defences, bridges and public utility services across the UK.

To mark 80 years since the end of the war, in 2025, Royal Mail released a commemorative stamp in Sir Thomas’ honour.

At 27, he secured his first independent post as city engineer of Ripon, where he worked for four years. During this time, he was responsible for building two river dams and extending the sewage disposal works.

He then held posts as city or borough engineer in Stockton-on-Tees, Plymouth, Cardiff, and Liverpool, spending three to four years in each role.

While in Plymouth, he was responsible for construction work, including roads and sewers for an extensive housing scheme.
