works over hormones extracting from several thousand liters of urine progesterone in 1934 and testosterone a year later. Subsequently, Butenandt had synthesized estrogen and testosterone. Adolf Butenandt also had characterized the first pheromone, bombykol, a chemically well-characterized sexual hormone released by the female silkworm to attract mates. While working in Gdańsk Butenandt has obtained a substantial part of research results awarded later by Nobel Committee in 1939. Chemical Faculty is one of five faculties, which started operations research and teaching in 1945, as a result of the decree of the Polish government transforming technical university acting in Gdańsk since 1904 into Polish Gdańsk University of Technology. To this day, it works in rooms designed specifically for training chemists, since 1904 operate here labs, preserved historic auditorium, which original equipment is unique in the world. In the period of 1945–2005 from the Chemical Faculty graduated more than 7000 people, including 4877 masters of engineering and 1967 engineers. PhD degree was given 565, and 97 DSc degrees (habilitations). A total of 43 professors have held posts at Gdańsk Tech during this time. The Chemical Faculty has worldwide research ties and ranks consistently among the top 10 Polish public colleges and universities in funded research. As early as in 1904 the laboratories in the Chemical Faculty at the Technical University in Gdańsk were equipped with wooden fume hoods. That was one of earliest applications of that kind in the world. Harmful and corrosive gaseous byproducts of reactions were actively sucked allowing safe operation with chemicals. There were used the natural draft of a fireplace chimney to remove these substances from the lab. This unique in the world equipment is well maintained and still in daily use for almost 120 years. At the faculty there are realized projects financed by the Komitet Badań Naukowych (Science Research Council) and European Commission. Faculty research teams collaborate with foreign centers from several countries. At the faculty operates the Centre of Excellence in Environmental Analysis and Monitoring. The Chemical Faculty's scientific activity is performed within the framework of domestic and international research programmes. There are around 70 ongoing projects with financial support from the Polish State Committee for Scientific Research as well as 200 projects financed by Statutory research programmes. There are also research programmes financed by the European Commission within the framework of EU programmes V and VI. International cooperation Gdańsk University of Technology takes part in
