R' Moshe ben R' Yaakov Cordovero, the Ramak (1570) was one of the most famous mekubalim. He studied nigleh under R' Yosef Caro and kabala under his brother-in-law, R' Shlomo Alkabetz. He wrote several seforim, including Pardes Rimonim and Tomer Devorah. The Satmar Rebbe had a kabala from the Divrei Chaim of Sanz that the sefer Tomer Devorah is a segula for the "known disease" may Hashem save us, and if one isn't able to learn it himself, he should have someone read it in front of him. (It is available in English translation)
R' Gedalia Ahron Kenig (1980), one of the leaders of Breslov, was a talmid muvhak of R' Avrohom Sternhartz, who encouraged him to establish Kiryat Breslov in Tzefas. His son, R' Elazar Mordechai Shlita, is the current leader of the community. R' Gedalia wrote Chayei Nefesh, on R' Chaim Volozhiner's Nefesh HaChaim, proving that there is no arguement between Chassidim and Misnagdim on the principles and foundations of Yidishkeit, as they are beyond dispute. Parts have been translated into English by Rabbis Dovid Sears and Dovid Zeitlin, of The Breslov Center, and are available for download (PDF) - Part 1 and Part 2. They are quite fascinating and explain a lot.
