Ferdinand Magellan was the first (at least his crew) to successfully lead an expedition to circumnavigate the world. (he died on the voyage, but ~3 sailors made it back i believe, forgot the number of sailors, but very little)
hope this helps

Both Leaders challenged the European Union.
And they both studied chemistry at universities.
Please correct me if I'm wrong!! :)
