The Ptil Tekhelet organization, which manufactures and distributes tzitzit, will hold a conference celebrating the revival of the ancient custom of the blue fringe. The 100 Years to Tekhelet Research conference will honor the 100th anniversary of Chief Rabbi Isaac Herzog's doctoral dissertation, The Dyeing of Purple in Ancient Israel.
Addressing the audience will be academics and scholars as well as Member of Knesset Isaac Herzog, a grandson of the late Chief Rabbi.
One of the Torah commandments is to wear tassels, or tzitzit on the corner of any four-cornered garments with a fringe of blue on each one. Today, most people wear white fringes, but over the generations, many have tried to rediscover the exact dye used in Jewish antiquity, two of the most notable being Rabbi Gershon Henoch Leiner, the Radziner Rebbe, who researched the subject in 1887 and later, Chief Rabbi Herzog.
