The EarthView blog often includes anniversaries related to geography. Today is the centennial of an event that is essential for EarthView itself. On April 29, 1913, Gideon Sundback received a patent for the modern zipper.
His design was an improvement on the work of others, but it was such a dramatic improvement in simplicity and reliability that Sundman is widely considered the inventor of the modern zipper. Last year his birthday -- also in April -- was recognized by a Google doodle.
As we mentioned when the EarthView zipper was replaced about a year ago, without the zipper, EarthView itself would be impossible. To keep the zipper working smoothly, the EarthView wranglers frequently apply natural beeswax to its zipper.
