It’s a sign of just how revered Carl Linnaeus is in Sweden that for many years many people had a picture of him, and his garden, in their pocket. That's because the botanist, who is famed for creating the two-name system for classifying plants and animals, adorned the 100-krona banknote for many years. It’s easy to visit the garden where he did his research, as the town of Uppsala can be reached in less than 40 minutes by train. The garden was originally laid out in 1655, then redesigned by Linnaeus in 1745. You can also visit his former home, now the Linnaeus Museum. As for the banknotes: In 2017 Linnaeus was replaced by Greta Garbo.
