Institut Teknologi Sepuluh Nopember or ITS (English: Sepuluh Nopember Institute of Technology) is a public university in Surabaya, East Java, Indonesia, focused in the higher education of science, engineering and technology. ITS took its name from the Battle of Surabaya which reached its peak on November 10, 1945. The day is also commemorated as Heroes day in Indonesia. The ITS acronym does not stand for Institut Teknologi Surabaya (Surabaya Institute of Technology), as some people think, but Institut Teknologi Sepuluh Nopember (November 10 Institute of Technology). In the first years of Indonesian independence the need for educated engineers was felt. In response, several members of PII (Indonesian Engineers Association) in East Java and Dr. Angka Nitisastro, a medical doctor, set up a foundation to start a technical college in Surabaya. Perguruan Teknik 10 Nopember Surabaya or November 10 Technical College was established in 1957. Its establishment charter was signed by Indonesia's first president, Soekarno. At first, ITS only had two departments, Civil Engineering and Mechanical Engineering.
