Pete is back.
Pete met his old friend Steve at the hospital at the end of March. They both went to the same history class.
Steve: Pete? Pete, is that you?
Pete: Yes. How are you? Haven't seen you in ages
Steve: I am fine. What about you?
The conversation went on for a while. They talked about a lot of things: how they both nailed that one history test without learning anything, how they went to France together for a summer, how they pranked their teacher, and which topic in their class they liked the most. They even both had a favourite scientist. For Steve it was Nikola Tesla.
Who is Pete's favourite scientist?
Since I'm not a native speaker it would be nice if you could help me to fix the grammar in this riddle. Please do not change the conversation.
