Wilhelm Reich was an Austrian psychiatrist and psychoanalyst, born in 1897. He is best known for his work in the field of psychology and his theories on human sexuality, which he explored in his book, The Function of the Orgasm. Reich believed that sexual health was essential for overall well-being and developed concepts like orgone energy, which he claimed was a universal life force. Reich's ideas were controversial and led to conflicts with the scientific community. He founded the Orgone Institute in the United States, where he conducted experiments and promoted his theories. His work has influenced various fields, including psychology, alternative medicine, and social theory.
