Hello Girls instance of profession
History of the term
Although the term "hello girls" may have been applied to the signaling corps, it did not originate there. Rather, the term was first coined for female telephone switchboard operators in the US, and was the common term used for women who would greet callers with "hello" when they rang the switchboard instead of dialing another telephone number directly. Published references to "hello girls" predating World War I include the following sentence from Mark Twain's A Connecticut Yankee in King Arthur's Court written in 1889: "The humblest hello-girl along ten thousand miles of wire could teach gentleness, patience, modesty, manners, to the highest duchess in Arthur's land".  Another source referenced gifts that the "hello girls" received at Christmas-time from local businesses in Flint.
