There is a magnificent museum in Rio de Janeiro called the "Museum of Tomorrow". This museum is known to have had exhibits of or about Alberto Santos-Dumont. Santos-Dumont's home in Petroplis is also a very fine museum.
Brazil is the home of Alberto Santos-Dumont, so one could expect that a display recognizing a native son would be present at all times at this museum though I was unable to confirm it. As with most all modern museums, the emphasis is not history, rather the emphasis is typically only on the "modern" hands-on displays to bring in paying guests. It is not unusual in modern museums to find airships completely neglected to make room for the "glitz and glamor" displays.

The home of Alberto Santos-Dumont has long been a museum. Though not an "airship museum", or a history museum with an airship exhibit or two, it is the home of Alberto Santos-Dumont!
