Frederik Louis Wilhelm Hellesen (2 February 1836 – 22 December 1892) was a Danish inventor and industrialist.

The same year a young chemist Valdemar Ludvigsen (1861–1939) came to the factory helping by the further development of the batteries.

When Frederik Hellesen died in 1892 his widow took over the company with the help of Ludvigsen.

In 1992 the Danish company was sold to GP Batteries International in Singapore belonging to Gold Peak Industries Ltd. Hong Kong.
