This list is works of my research, via online or by collecting string quartet recordings. I will by time to time try to edit and fix the format. However, I found this list already understandable enough. Please feel free to add in comments section, if you find missing composer, especially from Classical era. My previous list , I declared as supersede, replace by this one.
