Larry C. Olsen
From 1967 to 1972, Dr. Olsen led research efforts in betavoltaic and thermoelectric energy conversion as a Research Scientist at DWDL. He led a team in developing the Betacel, the first commercial betavoltaic nuclear battery for cardiac pacemakers.
For this ground-breaking work, the Tri-Cities of Washington State named Olsen the 1970 Tri-Citian of the year.[Since then, Dr. Olsen has continued to be involved in betavoltaic battery development, which includes consulting activities with government agencies.
