The Cedergren Medal is a rarely granted honor awarded to outstanding scientists in electrical engineering by the Cedergren Foundation. Only 14 have been issued since the recognition was created in 1914. Mathematics genius and electrical engineering pioneer Charles P. Steinmetz was the first recipient of the honor's silver medal.
In addition to funding the honor, the foundation, which was established in 1909, also uses its endowment fund's investment returns for scholarships to Swedish electro technicians. Namesake Henrik Tore Cedergren (1853-1909) was the founder of Stockholms Allmänna Telefon AB which merged with Lars Magnus Ericsson’s company in 1918 to become Allmänna Telefonaktiebolaget L M Ericsson. Today, Ericsson is the world’s largest mobile communication network provider, holding 35% market share.
