Ask HN: Inventors on the same level as Nikola Tesla or above him?

I personally feel that Nikola Tesla is a rare breed among inventors and I am inclined to believe there are only few who were on his level or above him in inventiveness.Till now I haven't come across anyone who has impressed me like Tesla. I would like to ask the knowledgeable folks here at HN as to who are those other unknown inventors who were at the level above or equal to Nikola Tesla.Please share as much information about them.It will be quite helpful to me and lot others on this forum. Thanks in advance.
