“oomis1105 – you think rabbenu gershom was MO?’
R’ Gershom ZT”L was a man who (according to what I was taught re: his takanah)unfortunately married two women and they made his life miserable. He wanted to ensure that other men did not fall into his tzoros, and he had the halachic koach at that time to make a takanah for a specific time (as I understand it), regarding the marrying of more than one wife. He also made the takanah that is is assur to open up and read other people’s mail. I would say that he had a certain visonary quality to him, which one could think of as MO, if one chooses.
