On this day in 1825, the United States Patent and Trademark Office issued its first patent for a system to "preserve animal substances in tin". Ezra Dagget and his nephew Thomas Kensett, the patent holders, had been canning salmon, oysters and lobsters out of their seafood processing factory in New York City since 1819. 

Tin cans had been put into use for preserving food since 1813, but their use had largely been limited to specialized environments and circumstances like military expeditions and arctic exploration, rather than commercial use.

Hagley is pleased to announce the release of 40 newly digitized radio episodes of The Ohio Story. This scripted radio and television program was broadcast live to a network of stations across Ohio from 1947 to 1961. Running for 15 years, it is believed to be the longest-running regional scripted program in the United States.

From the morning hours on September 14, 1960, a mass of people stormed the newly opened glass pavilion on the Square of the October Revolution, the center of the working-class neighborhood Trešnjevka in Zagreb. Unlike the historical event that the square was named after, the revolution in question was of a different kind—the opening of the first self-service department store in the Croatian capital after the Second World War. The opening of the store was one of the events that kickstarted the spread of department stores based on the self-service system in large Yugoslav urban centers.

From January 2 to 31, Nation of Inventors and the Museum Store are open. All other areas of Hagley are closed for seasonal maintenance and upgrades. Walking on the property is not permitted.

Usually we wouldn't recommend just casually searching the internet at work for things like "wife discovers the spice of life". But, as it turns out, it's just bread and cellophane.


This undated advertisement from DuPont promoted the company's cellophane. DuPont acquired U.S. patent rights in cellophane in 1923, but it was soon revealed that water vapor could penetrate the film. This fact precluded its use for food packaging.
DuPont scientist William Hale Charch (1898-1958) resolved this problem, and in 1927 a patent was issued for the moisture-proofing system. Cellophane continued to be highly profitable through the 1950s, but by the 1960s new products began replacing it. Cellophane production declined through the 1970s and early 1980s with DuPont discontinuing it in 1986.

Hagley Museum and Library (Hagley) collects, preserves, and interprets the unfolding history of American enterprise. Hagley is an indoor/outdoor cultural heritage site that explores the history of innovations in science, technology, and engineering through the du Pont story. 

Michelle Craig McDonald will speak at an Author Talk at Hagley on Thursday May 14 about her recent book, Coffee Nation: How One Commodity Transformed the Early United States. Coffee is so ever-present in our lives today that its roots are under-appreciated – especially the contributions of Philadelphia-based merchants in the very early days of our nation to coffee’s popularity.
