Rabbi Chiya רבי חייא

Transitional sage of the last tannaitic generation, born in Bavel and risen to the inner circle of Rebbi as senior student-colleague. With Rabbi Oshaya he assembled the collections of baraitot regarded as the most reliable outside the Mishnah — the core associated with the Tosefta — and the Talmud celebrates his one-man campaign to keep Torah from being forgotten. He was the uncle and first teacher of Rav, who carried his tradition back to Bavel.

"I act so that Torah will not be forgotten from Israel" — he sowed flax, wove nets, trapped deer to feed orphans and write scrolls on the hides, and taught each child one of the five Chumashim and each of six children one of the six sedarim, having them teach one another; Rebbi exclaimed "How great are the deeds of Chiya!" rabbinic ★★★★☆
Any baraita not taught in the school of Rabbi Chiya and Rabbi Oshaya is presumed corrupted (meshabeshta), and one may not adduce it in the study hall — the Talmud's standard for authoritative tannaitic material outside the Mishnah. rabbinic ★★★★☆
When Rav descended to Bavel, Rabbi Chiya presented him to Rebbi as "my sister's son going down to Bavel," securing his authorization to rule on matters of law and ritual; geonic tradition further records that Rabbi Chiya wrote the Tosefta as a supplement clarifying the Mishnah.
Sanhedrin 5a also cites a tradition that Rav was doubly his nephew (son of both his brother and his sister via half-siblings). The attribution of the Tosefta's redaction to Rabbi Chiya is geonic (Rav Sherira raises it as a received report) and debated by academic scholarship.
