However, there was an organization devoted solely to chemistry, which was a fast-growing science. Chemistry is the scientific study of substances, how they behave and change under different conditions, and how they interact.In 1874, several American chemists met at the home of Joseph Priestley to mark the 100th anniversary of his discovery of oxygen. The chemists that attended that event began discussing the idea of creating a new society that would focus on theoretical and applied chemistry.After two years of planning, 35 chemists met at the University of the City of New York (today New York University). On April 6, 1876, they officially established Americas first chemical society the American Chemical Society (ACS). At that first meeting, a constitution was adopted, officers were selected, and well-known scientist of the time John William Draper was selected as the first president.One of the founders, Professor Charles F. Chandler of the Columbia School of Mines, said the society would prove a powerful and healthy stimulus to original research,would awaken and develop much talent now wasting in isolation, members of the association into closer union, and ensure a better appreciation of our science and its students on the part of the general public.The goal of the ACS was to share chemical knowledge with the public and improve the industry benefits to mankind and the Earth. Within a year, they obtained a state charter and only a few years later, distributed the first ACS scientific journal.Now headquartered in Washington, DC, the American Chemical Society agenda is multifold. Its purposes are to advance science, advocate for innovation, enable career development, educate the public, support the future of the chemical industry and chemists, and to promote diversity in the field.Today, this nonprofit organization is the largest scientific society in the world with over 158,000 members. The ACS continues its mission with various publications and more than 30 different technical divisions dedicated to different aspects of chemistry. The society best-known publications include the Journal of the American Chemical Society, Chemical Abstracts, and Chemical and Engineering News. Powered By 3Dsellers.com - Try for Free!
