How about one paragraph each?
In the first paragraph you could write about his life.
You can include some of these facts:
Tesla was Serbian and he was born in Smiljan, at the time in the Austrian Empire, which is today in Croatia.
He studied in Graz, in Austria and was originally a really good and hard-working student there, but eventually he dropped ouf ot school due to a personal conflict. After more adventures, such as trying to study in Prague and working in Budapest,
he moved to the US.
The second paragraph could describe his work. include: Tesla's contribution to alternating current system, and the fact that he wanted to work on wireless electricity, and he predicted that one day a wireless communication will be possible.
hope it helped!
