Rabbi Dov Ber Levine, a shochet, corresponded with the Rebbe over several years, and was active in chassidic education and outreach, including for girls and women. No reliable published biography is available; the summary below is drawn from the letters themselves.
The Rebbe wrote to him about organizing farbrengens for girls in which each participant presents a Torah thought (IK 1955), and about preparing talks for Nshei uBnos Chabad gatherings (IK 6446). He advised on selecting chassidic stories and on Kehot publications in English (IK 3804), on teaching Chassidus in public (IK 4299), and on spreading the wellsprings, explained through the analogy of a spiritual spring (IK 4590). One letter also discusses the spiritual significance of choosing a name (IK 4170).
