Carrying the legacy of one of the most influential musicians of the 20th century into the 21st. Louis Armstrong was one of the most famous and influential musicians of the 20th century, known for his improvisational style that helped mold generations of music. Armstrong documented his own place in history through thousands of pages of collages, scrapbooks, letters, and journals, as well as hundreds of hours of voice recordings. The Louis Armstrong House Museum in Queens, where Armstrong spent the later part of his life, recently digitized its entire collection to make it more widely available to the public. It's also building a new Armstrong educational campus in Queens to carry the musician's legacy and influence into the 21st century. NewsHour Weekend's Megan Thompson has the story.
