The company was founded in Parma in 1935 when Giacomo Chiesi, a chemist who dreamed of doing research, bought the Laboratorio Farmaceutico Parmense and embarked on his entrepreneurial adventure. In the early forties the laboratory started to expand and sell its products abroad. During the war part of the company was destroyed during a bombing raid, bringing all activities to a stop until the war ended. After the war in 1955 Giacomo Chiesi build a real factory with 50 employees.
In 1966 Giacomo Chiesi handed over the management of the company to his two sons Alberto and Paolo. Chiesi Farmaceutici was a small company at that time, yet already looking towards international markets.
Alberto and Paolo started a continuous expansion and internationalisation process by opening the first office abroad, in Brazil in the late seventies. Today the Group’s international expansion is very strong, with direct presence in 26 countries and exporting in 70 countries.
The third Chiesi generation joined the company between the end of the second and the beginning of the third millennium: Alessandro, Andrea, Giacomo and Maria Paola. Their input opened up new lines of research and development: the Modulite® technology for respiratory products with eco-friendly sprays like Foster and the development of the NEXTHaler®, dry powder inhaler, considered the most innovative device in its class. In 2008, Chiesi entered as a pioneer in the world of regenerative medicine by founding Holostem Advanced Therapies Ltd, and in 2013, with the acquisition of the Danish biopharmaceutical company Zymenex, moved into biotechnology, positioning itself today at the height of innovation in the bio-pharmaceuticals sector.
