Final answer:
Neil Armstrong, the first man on the moon, enjoyed playing the ukulele, particularly during his quarantine period after the Apollo 11 mission.
Step-by-step explanation:
The first man on the moon who loved to play the ukulele was Neil Armstrong. After Armstrong's historic moon landing on July 20, 1969, he, along with fellow astronauts Buzz Aldrin and Michael Collins, were placed in quarantine to ensure they had not brought back any harmful lunar bacteria. Armstrong was known to strum his ukulele during this quarantine period.
