R. Jonah was a thirteenth-century scholar who lived in Spain. Although originally opposed to Maimonides’ philosophical works (most notably, his Guide for the Perplexed), he later changed his views, and even vowed to travel to Maimonides’ gravesite to posthumously beg for forgiveness. (He indeed began the long journey, but passed away before completing it.)
R. Jonah authored Shaarei Teshuvah (an ethical work on repentance), a commentary on R. Isaac Al-Fasi’s halachic compendium, and a commentary on Ethics of the Fathers, among other works.
Others date his passing as 1 or 28 MarCheshvan.

Each generation has its role in history.
From all the generations before us we inherited a wealth of dreams: philosophy, truths, wisdom and purpose. We are tiny dwarfs standing on the shoulders of their ideas and their noble deeds.
Our generation’s mandate—and destiny—is to make the dream real.
