Early Improvements in Fountain Pen Design
1884 Lewis Edson Waterman produced the first practical fountain pen with self contained ink storage.
this pen was capable of being filled externally and contained ink storage that automatically flows to
the nib point.
1890 Rubber sacs were used to hold ink within fountain pens.
1920 Long-lasting rubber sacs were introduced.
1932 First sacless pen was manufactored by Parker Pen Company.
Thanks for posting this breif synopsis of fountain pen history. I don't want to be overly critical, but two items need comment:
The Waterman feed was a very good feed design and you can more-or-less give credit to LEW for inventing the modern feed. However, Paul Wirt had several equally effective feed designs that went alongside the LEW feed, and it was actually a number of later modifications of the basics of the Waterman feed that made it the fore-runner of most modern feeds.
But Parkers claim for the first sacless pen is a bit of advertising fluff on the part of Parker. For one, they claimed the vacumatic was "sacless" when in fact it had a sac, just a funny inverted one they called a diaphragm. But more importantly, there were sacless, self-filling pens designs that pre-dated not just Parker, but even Waterman's first pens. The original Prince's "Protean" pen from 1865 was a syringe-filler. Syringe-filling pens, which have an even stronger claim to being "sacless" in that they do not have any rubber diaphragm at all, were made by Franklin and Eagle, among others, in the first decade of the 20th Century. So there were sacless self-filling pens long before Parker's Vacuum-fil.

PS - Richard, I just noted that your location is listed as Philadelphia. I grew up outside that city. If you are not already aware of them, you might be interested in checking out the Franklin Pen Co. that I referenced above - they were an early Philly pen company. There are a few of us here that are interested in Franklins.
