, the JEM-1, a year later. Overseas sales began in 1956 with the sale of a system to France. The company's strengths were the customization of orders to fit customer requests, and the provision of strong customer support. In 1961, the company was renamed JEOL, Limited. Its first overseas subsidiary, JEOL Company (USA) Inc., was established in 1962 and headquartered in Peabody, MA. JEOL was listed on the Second Section of the Tokyo Stock Exchange by 1962, and on the First Section of the Tokyo Stock Exchange by 1966. The company expanded from electron microscopy to nuclear magnetic resonance (NMR), releasing the first NMR system in Japan, the JNM-1, in 1956. They produced their first

in 1966. In 1968, they produced the first amino acid analyzer in the world, the JLC-5AH. The company also continued to develop its line of electron microscopes. The JEM-7, in 1964, was the first electronic microscope to include a mechanism for the electrical adjustment of the lens axis. The JEM-100B incorporated an electromagnetic deflection unit as well as an electromagnetic stigmator. The first photomicrograph of atomic arrangement in the world was taken by a JEOL electron microscope, in 1976. Kazuo Ito has expressed the company's philosophy as follows: In commemoration of JEOL's 20th anniversary, the Kazato Research Foundation was created to support electron microscopy research. Kenji Kazato retired as president of JEOL in 1975, but continued to act as an adviser to the company until his death in 2012. Kazuo Ito was JEOL's president from 1982 to 1987. The Pittcon Heritage Award was posthumously awarded to them in 2016 for their contributions to scientific instrumentation. In 2014, a STEM resolution of 45 pm with a 300 kV microscope was first demonstrated with the atomic transmission electron microscope JEM-AMM300F.
