Short summary
The Liverpool Tidal Institute's (LTI) 100th anniversary was in 2019, and it acquired a reputation using tide prediction machines (TPMs). We describe the principles of a TPM, how many were made and Doodson's method to determine harmonic constants from tidal data to predict the tides. Although only three TPMs were used at the LTI, Doodson oversaw the design and manufacture of several others. We show how the UK, and Doodson particularly, played a central role in this area of science.
