One idea could be to plan a weekend getaway to a city known for its historical tours, such as Washington D.C., Boston, or Philadelphia. You can book a private historical tour with a knowledgeable and experienced guide to take your husband through the city's significant landmarks, historical sites, and museums. Alternatively, you can give him a book of historical tours so he can plan out his own tours in a city he is interested in visiting. Additionally, you could get him a personalized historical artifact or memorabilia from a significant moment in history that he is particularly interested in.
Or you can get him a star map with the date when he was born.
