As a special shul project--and with the generous permission of Aguath Israel and Yated Neeman--we are going to begin featuring biographies of Gedolei Yisroel on our shul website.

Of course, the question arises whether there is anything to be gained by this.
The following articles address that question:

• Jewish History by Rav Shimon Schwab zt"l
• Are Gadol Biographies Good For Us? by Jonathan Rosenblum
• See also "Why History?" by Rabbi Berel Wein

The articles are divided according to where the Gedolim lived:

• American Gedolim
• Baalei Mussar
  
• Chassidic Gedolim
  
• European Gedolim
• Great Leaders
  
• Great Women Leaders
• Rishonim
  
• Sefardi Gedolim

There is also a list of Gedolim in alphabetical order
