Rav Chaim Soloveitchik (1853 - July 30, 1918) was born in Volozhin to his father, the Beis HaLevi, who taught in the famous Volozhin Yeshiva. Rav Chaim began to teach Gemara using a new method known as the Brisker method of learning. Every halacha is analyzed and classified like a scientist. This helps talmidei chachamim understand the Gemara and halacha better. This method of learning is now used in all modern yeshivos. Rav Chaim created a new vocabulary so that everyone could understand the Gemara better.
Rav Chaim Brisker changed Torah learning all over the world. Yet, at the time he was niftar, this was not what was remembered the most. What everyone remembered was his chesed. Rav Chaim’s house was open to all. In Rav Chaim’s living room, beggars would put notices up on the wall. They would sleep on his couches. He would always be careful not to disturb them. On his matzeiva was written the description, "Rav HaChesed."
