<<Doron Beckerman claims that the Chofetz Chaim and Rav Moshe Feinstein<br>are "the two most influential<br>Poskim in post WWII Jewry."<br>Rav Ovadiah? Rav Shlomo Zalman? etc.<br>Also, if as has been mentioned here before the influence of the

</a> -- then perhaps it<br>makes more sense to view Rav Kotler and the Chazon Ish as among the<br>most influential poskim.>><br><br>In any case the MB is from the 19th century and why count it more than SA.<br>My personal vote for the 2 most influential modern poskim are the Chazon Ish
<br>and RMF. Certainly in Israel Chazon Ish is the most influential posek.<br>RAK was basically a RY and not a posek. RSZA would be my second choice<br>in hilchot shabbat. However, when it comes to modern shailot in 4 parts of SA
<br>I think that RMF was the most innonative. Just as a trivial example consider the<br>question of saying birkhat hagomel for a flight. Most poskim compare it to going<br>over water and apply the old criteria. RMF redefines what it means and flying
<br>is doing something unnatural. Similarly with kitniyot RMF goes to the<br>basic question of the gezara while the others try and decide if cottenseed is called<br>kitniyot etc ...<br clear="all"><br>-- <br>Eli Turkel
