The SOL Group was founded under the management of Giovanni Annoni and Aldo Fumagalli, with two initial plants for the production of oxygen and acetylene based in Livorno and Ancona.


Alessandro and Renzo Annoni, Giulio and Ugo Fumagalli Romario, the second generation, launched an ambitious project for the innovative development of SOL: these were the years of the first technical gas production plants, located close to the Group’s major key customers, such as steelworks and glass-makers.


SOL became a leading player in the sector in Italy thanks to the transition from a regional market strategy to a national one. This was made possible by embracing the major transformations taking place in the technical gas industry at the time due to the development of technologies for the storage and distribution of gases in cryogenic liquid state. 


The Group also began to grow in Europe, creating plants, branches and joint ventures in most European countries over the years, also seizing opportunities offered by the opening of new markets in south-east Europe.


SOL was one of the first companies in Europe to introduce a new form of treatment, developed in the US, for patients affected by serious respiratory disorders.

In order to be more competitive on the international markets, the Parent company SOL Spa was listed on the Milan Stock Exchange. The arrival of the third generation of the Annoni and Fumagalli Romario families at the helm of the company, together with a young executive management team from outside the families, allowed the Group to pursue its internationalisation strategy.
