Radia Perlman was named a Sun Fellow. That’s just above Distinguished Engineer and right below
Techno-God. I think she is qualified for the latter, but it takes some time for the paperwork.
She is perhaps best known for the creation of the Spanning-Tree algorithm that is used in all network bridges and switches, but continues to work on neat and interesting stuff in a department that has nothing (alas) to do with me. Radia is sometimes referred to as “The Mother of the Internet”.
