In 1902 ''Seth Sears Crocker'' founded in Boston the ''Crocker Pen Company''. At that time companies were founded almost always following the completion of some technical innovation, for [[Crocker]] this was a new filling system called ''[[blow filler]]'' as based on compression of a rubber sac to be carried out by blowing into the body of the pen by a hole on the bottom.
