Edward R. Murrow was a man who worked on TV and radio a long, long time ago. He was very famous because he talked about important things that were happening in the world, like wars and politics.
One of his most famous things was when he talked about a man named Joseph McCarthy, who was telling people that there were lots of bad spies working in America. Murrow didn't think this was true, so he used his TV show to tell people that McCarthy was making things up.
This made a lot of people really happy because they didn't trust McCarthy either. Murrow also talked about other things that were happening around the world, and people really trusted him because he always told the truth.
