The sad story of Guillaume Le Gentil, who missed the transit of Venus reading in 1761 because his ship was blown off course and stranded at sea for several weeks. When he finally arrived at Pondicherry, it was occupied by the British at the time. Then, in 1769 in Manila, for the second and last transit until 1874, although the skies were clear for the month before, it was overcast on the day of the transit.
When he finally got home 2 years later, his wife had remarried and his property seized as he had been legally declared dead.
