'Albert Einstein' is an anagram of 'Ten Elite Brains'. Einstein's lowest grade in school examinations at the age of 17 was in French.
On first seeing him, Einstein's granny is said to have muttered, "Much too fat, much too fat."
The famous photo of Einstein with his tongue sticking out was taken on his 72nd birthday by Arthur Sasse.
He was fed-up after being asked so many times that day to smile for the camera.
In 1930, in collaboration with the physicist Leo Szilard, Einstein received a patent for a type of refrigerator they'd invented in 1926. It never went into production and probably didn't work very well.
The chemical element einsteinium was discovered and named after Einstein in 1952. It has no known practical uses.
Einstein never wore socks and he never used shaving soap. He knew it was water, not soap, that softens the beard.
Einstein left his brain to science, and after he died in 1955 it was removed without his family's permission and taken away in a jar by Thomas Stoltz Harvey who conducted the autopsy.
Harvey sent slices of the brain to various scientists to study, but in 1998, at the age of 85, tired of looking after what he saw as a holy relic and handed it over to Princeton University.
"The hardest thing in the world to understand is the income tax." (Albert Einstein).
According to a diary kept by Einstein's friend Johanna Fantova, he was given a parrot as a present for his 75th birthday.
After disgnosing the parrot as suffering from depression, Einstein told it bad jokes to cheer it up.
