Rav
Shlomoh Taitelbaum Shlomoh Taitelbaum studied in Ner Israel Rabbinical College in Baltimore
and Yeshivas Toras Moshe in Jerusalem. He spent the better part of three

and Talmudic aspects of the re-identification of the coveted dye. He

Rav
Eliyahu Tavger Rav
Tavger is the Rabbinical advisor of the Ptil Tekhelet Association. His involvement with tekhelet began in his kollel
studies during which time he published his first work on tekhelet in the
Journal Moria, with the blessing of HaRav Hagaon Shmuel Auerbach
S”hlita. Further in depth research of the subject led to the
publication of his seminal work “Klil Tekhelet”. In 1988, his
research culminated in the first ever dyeing of tekhelet for the mitzvah of
tzitzit from the Murex trunculus since its disappearance 1300 years
prior. Rav Tavger then joined the founders of Ptil Tekhelet to become
the organization’s guiding light. In
addition to his efforts with the Ptil Tekhelet Organization, Rav Tavger has
been teaching in Moscow in Yeshivat Torat Chaim founded by HaRav Hagaon Moshe
Soloveitchik ZT”L and currently under the auspices of HaRav Hagaon
Aharon Leib Steinman S”hlita. Rav Tavger resides in Kiryat Sefer with
