Which US Presidents travelled around the world?

Question

Shortly after President Grant left office, he went on a round-the-world journey, with stops all over Europe, in Russia, through the Suez Canal, to China and Japan, arriving in San Francisco and then crossing the North American continent.

I believe he was the first US President (or former President) to do so. Please correct me if I am wrong.

I am guessing such journeys have become more common as travels have gotten easier and cheaper (Grant spent something like $25,000 for his journey).

Which other Presidents have made a round-the-world journey as a single trip?

My information about President Grant is from Jean Edward Smith's wonderful Grant.

Answer 1

Franklin Pierce beat Grant by a decade...

After Office..

• in 1857 Franklin Pierce retired from the presidency and left on a grandiose vacation to Madeira, Portugal, Spain, France, Switzerland, and Rome, where he met up with his longtime buddy, Nathaniel Hawthorne.

• In 1913 — four years after he left the Oval Office — Teddy Roosevelt took part in an expedition to South America, promising to hunt and bring back animal specimens for display in the American Museum of Natural History. He caught Malaria and nearly died.

In Office

• Theodore Roosevelt was the first commander in chief to travel outside the U.S. on official business, when he sailed to Panama in November 1906.
