John Jacob Loud was an American inventor known for designing the first ballpoint pen. Trained as a lawyer at Harvard College, Loud worked at the Union National Bank in Weymouth, Massachusetts as a cashier. He was also active in his community as a member of his church, a trustee of many local organizations, and a member of local historical societies. Loud invented and obtained a patent for what is considered to be the first ballpoint pen in 1888; however, his invention was not commercialized and the patent would eventually lapse. The modern ballpoint pen would be patented later in 1938 by László Bíró, 22 years after Loud's death.
