Rabbi Chananya Ben Tradyon was one of the Asara Harugey Malchus - 10 Leading Sages that were muredered in a torturous fashion by the Romans to attone for the selling of Yosef.
RCB"T is buried (I think) just outside of Tsfas (Safed).
The Talmud (tractate Avoda Zura 17b) says that RCB"T was punished for pronouncing the Shaim Hamiforash - special Divine Name (only pronounced by the High Priest on Yom Kippur in the Holy of Holies) publicly (he did it to learn, otherwise this is something that one God forbid loses their portion in the future world). According to the Kabalists (quoted by the RA"K obm) this in fact was the way of Father Abraham, as the Torah itself states explicitly that Avrohom Uvinu called in the Name of God. Apparently what was proper and exemplierary for Father Abraham was not for RCB"T. That is why H"Y in his great mercy gave us the Holy Awesome Name - Na Nach Nachma Nachman MeUman - to say, sing, and publicize as much as possible!
The Romans wrapped RCB"T in a Torah scroll and put wet wool over his chest to prolong his agony. His students told him to open his mouth so that he would die quicker, but he refused. RCB"T told his students that he saw the letters of the Sefer Torah flying in the air, as the parchment was burned. When the executioner offered to take away the wet wool if he was guaranteed a portion in the future world, RCB"T agreed, the executioner immediately made the fire even stronger, took off the wet wool, and then he himself jumped into the fire. A Bas Kol - Heavenly Voice rang out announcing that RCB"T and the executioner were welcomed into the Future world. Regarding this Rabbi Yehuda Hanassi cried and said, there are those that acquire the future world in one moment! From here we see the magnitude of doing the Tzadiks bidding!
Great blessings of Na Nach Nachma Nachman MeUman!
