Albert Einstein and his remarkable memory (or lack of it), are legendary.
There are a few far-fetched stories, like the one about him returning to his office and reading his own “GONE TO LUNCH. BE BACK IN 10 MINUTES” sign.
Or, how he lost his way one day, when going back home. He called up a taxi and told him-- "please take me to Albert Einstein's home" (knowing that all taxi drivers knew the house of a great scientist called Albert Einstein).
