Where to start? At least by limiting it to 400 years, you’ve cut down the potential list from possibly thousands to hundreds of pages, though I’ll limit mine to a little less than that. This should allow you to focus on some individuals without just throwing a long catalog at you, but any reader of this is welcome to add other names to this subjective, chronological list. Beyond the famous, there are also numerous unsung heroes who can serve as great role models, probably including people you see in your daily life, but I have limited my choices to people whom you can easily research and study.
Morality plays a central role in Judaism, and serves as a fundamental barometer of one’s true religiosity. The following figures have accomplished great feats in their lifetimes, while generally standing as beacons of morality and goodness. To read more about these role models, especially if I haven’t suggested a biography, do an online search which can lead you to essays or books about them.
17th Century
Maharal of Prague (technically, he’s just beyond 400 years as he died in 1609, but he’s such a towering figure that I am breaking the rules here) – a great rabbi and leader for all Jews
Gluckel of Hameln – inspiring woman who overcame many challenges – please read her autobiography
18th Century
The Ba’al Shem Tov – founder of Hasidut, who gave great hope to thousands of Jews, and began a positive, religious revolution
Rabbi Levi Yitzchak of Berditchev – great Hasidic master who always defended Jews
;
19th – 20th Centuries
Rabbi Yisrael Salanter – created movement to stress ethics and morality at all times – like Franklin, some of his followers would also write down their flaws daily in order to improve daily
Rabbi Yisrael Kagan (the “Chafetz Chaim”) – brilliant scholar who stressed the evils of gossip, known for his great sense of ethics and humility
Rabbi Abraham Isaac Hacohen Kook – first Chief Rabbi of Palestine, known for his great love of all Jews, regardless of background or observance
Hannah Senesh and the founders of “NILI” – courageous young Jews who paid with their lives trying to save lives of Jews in Europe and Israel before the establishment of the State of Israel
Holocaust - "Hasidic Tales of the Holocaust" by Yaffa Eliach to learn about Jewish heroism in the midst of the greatest evil imaginable.
David Ben Gurion and Golda Meir – two of Israel’s founders and great leaders (I really could add the tens of others who played crucial roles in establishing Israel – hopefully, you’ll be inspired and read about people like Menahem Begin and Mickey Marcus, or watch the movie about the latter, “Cast a Giant Shadow”)
Rabbi Aryeh Levin – great Jerusalem rabbi who gave great comfort to Jews imprisoned by the British (read the wonderful biography, “A Tzaddik in Our Time”)
Eli Cohen – incredible Israeli spy in Syria, whose work played a crucial role for Israel’s security – read “Our Man in Damascus”
Yoni Netanyahu – the hero of the Entebbe rescue whom you can read about in “The Letters of Yoni Netanyahu”)
Professor Nehama Leibowitz – great Bible scholar and pedagogue, known for her great humility (there are a number of biographies on her)
Natan Sharansky – Prisoner of Zion who defeated Soviet tyranny – read his “Fear No Evil”
As mentioned, these are but a few examples of the role models, both past and present, who should give us inspiration and help us reach our goals of being the best Jews that we can be. Enjoy your journey.
