If I want to be a research scientist, do I also have to be a professor and give lectures?

I love investigating, learning, reading, writing, experimenting and discovering new ideas! This is a solitary process which I enjoy. The thought of having to give lectures as a professor is the most exhausting concept in the world to me, this seems like the opposite of research. I have heard that you must be affiliated with a university to get funding etc. which means giving lectures.. is this true?
