ELI5: Explain Like I'm 5

Arthur C. Lundahl

Arthur C. Lundahl was a very smart man who worked for the United States government. He was really good at looking at pictures and figuring out what they meant.

When bad things were happening, like when other countries were trying to hurt the United States, people would give Arthur pictures to look at. He would study these pictures very closely and figure out important information. Sometimes, this information helped the government to know what the bad guys were planning, so they could stop them from hurting people.

Arthur was so good at looking at pictures that he was very important to the government. He even earned a special award from the President of the United States for his work.

Even though Arthur has passed away now, his work and the things he figured out about pictures still help keep people safe.
