Yes, Fleming's Triangle, as in Willamina Fleming. Born in Scotland, she initially served as a maid in the household of Edward Charles Pickering, director of the Harvard College Observatory.
You see where this is going.
Pickering's wife Elizabeth, according to the reliable Wikipedia, sensed that Willamina had talents beyond dusting, laundry and childcare. So Professor Pickering initially hired her for administrative work, then anointed her as one of his cadre of "computers" -- i.e., women who understood mathematics. In 1904, Fleming discovered the "triangle" in the Veil nebula.
Which, by tradition at the time, Pickering named for himself. After all, she was only a computer, and he was director of HCO.
That was then. This is now. Let's give credit were credit is due and rename the thing Fleming's Triangle.
Here's my version, reprocessed from 2010 data:
