And what observations have been made in the 100 years since 1919?

[John Locke]

Very few, as it happens. The only other (more detailed) experiment with the Sun was in 1922. Scientists still use gravitational bending, but to estimate the mass of a remote body by measuring the bending of light, which of course is not a test of Einstein at all, merely putting the numbers into the formula.

Incidentally, there is a much simpler explanation of the phenomenon: that light travels more slowly in a gravitational field, as was proposed by Poincare in the 19c. The bending then follows directly from the Least Time theorem of Heron of Alexandria; it's an exercise in the Calculus of Variations a schoolboy can do.
