You're right, there aren't many scientists with names starting with Q. This is likely because "Q" is a relatively uncommon letter in names. However, here are a few examples:

* Quillian, Ross: American computer scientist known for his work on semantic networks and natural language processing.

* Queen, Elizabeth: This is a bit of a stretch, but Queen Elizabeth II was known for her support of science and technology.

Do you have a specific scientific field you're interested in? Knowing that could help me find more relevant examples.
