Parker fountain pen patent

In 1899, George Safford Parker was issued a U.S. patent on the first fountain pen he developed after experimenting to produce a more reliable design than those previously available from other manufacturers. Two years later in Feb 1892, the Parker Pen Company was incorporated, funded with $1,000 from his partner, William Palmer, an insurance broker. Parker continued making improvements, and filed several more patents. Then, patented on 4 Dec1894, the Lucky Curve design became the foundation for the Parker Pen Company's first significant success because of its improved ink feed that avoided spillage in the cap while being carried.
