Frank Shuman
Frank Shuman (; January 23, 1862 – April 28, 1918) was an American inventor, engineer and solar energy pioneer known for his work on solar engines, especially those that used solar energy to heat water that would produce steam. Career In 1892 Frank Shuman invented wire glass safety glass. Additional patents were issued relating to the process of making wire glass and machines for making wire glass.

19th-century American Inventors

''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words.
