In 1900, the Austrian neurologist Sigmund Freud published his book (written in 1899) "The Interpretation of Dreams". Sigmund Freud, born Sigismund Schlomo Freud in May of 1856, is the "father of psychoanalysis". Although he was a medical doctor, he was fascinated with the psyche and hypothesized the existence of the id, the ego, the superego, the libido, the unconscious, the Oedipus complex, and more. These are concepts that are still used by modern psychology.

In 1921, in May, the Emergency Quota Act - or Emergency Immigration Act - was passed. The law restricted the number of immigrants to 357,000 per year. It also established an immigration quota in which only 3 per cent of the total population of any ethnic group already in the USA in 1910, could be admitted to America after 1921. Although the Act was supposed to be temporary, it stayed in effect until 1965.
