This Shabbos, 24 Iyar, is the 28th yahrzeit of R' Binyomin ben R' Menachem Mendel Mendelson, Rov of Komemiyus. He was one of the founders of Moshav Komemiut, in Eretz Yisroel, which was one of the first moshavim to keep the laws of shmita. See here for the famous story about how their crops grew better after shmitah than the ones who didn't observe shmitah. Interestingly, his yahrzeit this year comes out on Behar-Bechukosai (he died the Monday after this parsha), where it talks about shmitah and the blessings that come through it's observance. This is testament to the deeds of this great Rov.
Also the yahrzeit of:
R' Yaakov ben R' Yaakov Moshe Lorberbaum of Lisa (his father died berore he was born, hence, the name), wrote Chaavas Daas and the Nesivos. Great-grandson of the Chacham Tzvi.
R' Eliezer Tzvi ben Yitzchak Issac Yehuda Yechiel Safrin of Komarna (1898), wrote Damesk Eliezer on Zohar
