Albert Einstein's diaries that he wrote during his travels around Asia and the Middle East between October 1922 and March 1923 have revealed to have racist views.
Einstein was a German-born theoretical physicist who was famous for his influence on the philosophy of science.
The dairies have been published in English for the first time, and reveal negative generalisations, such as calling the Chinese "industrious, filthy, obtuse people", the BBC reports.

Einstein travelled through the Middle East and then to Ceylon, China and Japan.
According to the BBC, Einstein described arriving in Egypt and facing "Levantines of every shade... as if spewed from hell".
He also describes his time in Colombo, writing, "They live in great filth and considerable stench down on the ground, do little, and need little."
But Einstein's most cutting comments were on the Chinese. According to The Guardian, he describes Chinese children as "spiritless and obese".
Einstein's views on racism changed over the years as he then went on to advocate for civil rights in the US.
In 1946, Einstein gave a speech at Lincoln University in Pennsylvania in which he called racism, "A disease of white people", and said he wouldn't keep quiet about it.
