The First Marine Chronometer 

My family and I are direct descendents of John Harrison, through my Great Grandmothers side, grandmother then my mother, he was my great grandfather 4 times removed i think it was :) i have all certificates and family trees etc if people wanna see :)

This is one of the most important inventions in British history.

Incredible pieces of engineering well worth a look if youre in south London

John Harrison received more money than any other individual, with several rewards from the 1730s-1750s, and £10,000 in 1765. In total, Harrison received £23,065 for his work on chronometers. He received £4,315 in increments from the Board of Longitude for his work, £10,000 as an interim payment for H4 in 1765 and £8,750 from Parliament in 1773.

you left out the fact that Harrison was never paid the full prize money, the English gov reneged on the deal
