Organized scientific expeditions to observe solar eclipses became more prevalent from the 18th century. Edmond Halley's precise calculations for the 1715 eclipse over England facilitated detailed observations. Captain James Cook documented a total solar eclipse in Newfoundland in 1766, reporting his findings to the Royal Society. The Royal Society actively funded and supported later expeditions, including those for Frank Watson Dyson in 1901 and the crucial 1919 expeditions to test Einstein's theory of relativity.
