Dr. Hulusi Behcet (1889-1948) is a famous Turkish dermatologist. He was born in Istanbul on February 20, 1889. His father was Ahmet Behcet and his mother Ahmet Behcet was also Ahmet's cousin. After the Turkish Republic was established and the "Family Name Law" was accepted, his father Ahmet Behcet, who was among the friends of Mustafa Kemal Ataturk, the founder of Turkish Republic, received private permission to use his father's name Behcet. Dr. Hulusi Behcet pursued his education at Gulhane Military Medical Academy. After he had become a medical doctor, he specialized in dermatology and venereal disease at Gulhane Military Medical Academy and he completed his specialization in 1914. His first observations on Behcet's Disease started with a patient he met between 1924-1925. Dr. Behcet followed the symptoms of three patients whom he had had for years, then he decided that they were the symptoms of a new disease (1936). He published these cases in the Archives of Dermatology and Veneral Disease. He died from a sudden heart attack on March 8, 1948. Today, this disease is universally called Behcet's Disease in medical literature.
