Rachel Carson
Her biology mentor from college helped her get a part-time job with the U.S. Bureau of Fisheries.  Here she wrote for a educational broadcast called Romance Under the Waters on the radio (this was before television).  It was a seven-minute program that ran once a week for a year. It was about aquatic life (mostly fish), to increase public interest in fish biology and in what the Bureau of Fisheries did. This was a job several people before Carson had not been able to do.  Carson also began submitting articles on marine life in the Chesapeake Bay to local newspapers and magazines.
