Tennyson had a personal relationship with Queen Victoria and her husband – a pretty big deal for an Englishman in the 19th century (source).
Tennyson waited fourteen years (!) to marry his wife, Emily Sellwood (source).
Tennyson published his first poems before he was 18, and continued to publish into his 80s (source).
Tennyson made more than 8,000 pounds in a single year from sales of a book of poems called "Enoch Arden." This was a huge sum of money at the time, as much as the wealthiest men in England would make in a year (source).
