Adnan Oktar
Adnan Oktar (born 2 February 1956), also known as Harun Yahya, is a Turkish author as well as an Islamic creationist. In 2007, he sent thousands of unsolicited copies of his book, The Atlas of Creation, which advocates Islamic creationism, to American scientists, members of Congress, and science museums. Oktar runs two organizations of which he is also the Honorary President: Bilim Araştırma Vakfı (literally, "Science Research Foundation", BAV, established 1990), which promotes creationism and Milli Değerleri Koruma Vakfı (literally, "National Values Preservation Foundation", established 1995) which works domestically on a variety of moral issues.
In more recent years, Adnan Oktar has been known for his televangelism on his TV channel, A9 TV, noted especially for featuring 'kittens', his female devotees. His organization is commonly referred to as a cult, and he has been described as the "most notorious cult leader in Turkey." Oktar filed more than 5000 lawsuits against individuals for defamation in the last decade, and led to blocking of a number of prominent websites in Turkey.
