Methods of Modern Meditation Masters

There are some very influential meditation masters of the 20th century such as Mahasi Sayadaw and S.N. Goenka who have many people today who follow their methods. Is it possible to summarize the methods particular to modern meditation masters (type of meditation, etc.) and provide links to their teachings? This might be helpful to those new to meditation or those looking to expand their understanding of the many styles of meditation available today. This is a community wiki and a work in progress. Please consider adding your knowledge to this post. Thank you!
