In addition to all the usual suspects folks have mentioned, there are some more big names worth pointing out.

• Elizabeth Anscombe coined the term "consequentialism" and was one of the most influential moral theorists in the history of the world.

• Simone Weil wrote a lot of interesting socialist theory.

• Martha Nussbaum (and her student Christine Korsgaard) have done tons of great work on both Ancient philosophy and moral/political philosophy.

• Mary Wollstonecraft's work on feminism and equality was foundational to our modern understanding.

• Nancy Cartwright was one of the best philosophers of science of the 20th century, period. A Dappled World is just brilliant.

• Judith Thompson was a towering moral philosopher who wrote probably the most influential piece on abortion rights ever

• Heather Douglas is one of my favorite living philosophers of science, and has some brilliant things to say about the relationship between science and society/values

• Wendy Parker has some of the best recent work on the foundations of climate science around

There are so many. That's all just contemporary people.

ETA: And, as far as I know, none of these people are sex pests. Hard to list that many comparable male philosophers without getting at least a few!
