Editing Rabbi Mordechai Dovid Altein

Born on 5 Tammuz 5679 (1919) in [[the United States]] to R' Tzvi Hirsh and Chana Altein, who were from a Galician chassidic family. He studied at Torah Vodaas Yeshiva and became close to Chabad chassidus at Achei Tmimim Yeshiva through Rabbi Israel Jacobson (who later became his father-in-law). He subsequently traveled with a group of bochurim to the yeshiva in Otwock. When the war broke out, the bochurim returned to the United States under the instruction of [[The Rebbe Rayatz|the Frierdiker Rebbe]].

In 5703 (1943), he entered into shidduchim, and at the tenaim celebration held on Motzei Shabbos, 18 Elul in the shul in East New York, the Rebbe and Rebbetzin participated. During the celebration, the Rebbe took a taxi home to bring the nusach of tenaim that the Tzemach Tzedek had written in his own handwriting.

In 5704 (1944), he married his wife Rachel Dvasha, daughter of Rabbi Israel Jacobson.

After his wedding, he managed yeshivas in New Haven and Pittsburgh as a shliach of the Frierdiker Rebbe. Later, he was sent by the Frierdiker Rebbe to the Bronx, where he managed a yeshiva and school and served as a community rav for many years.

He merited to bring many Yidden closer through his activities as director of the Chabad House in the Bronx.

The Frierdiker Rebbe writes about him in a letter: "A precious, internal, and naturally serious spirit, with abundant blessing. He is among my chosen beloved ones whom I love with special love, one portion above others of his age, for their dedication to their assigned work with true mesirus nefesh."

After his father-in-law Rabbi Jacobson's passing in 5735 (1975), he merited to bring the Rebbe an esrog from Calabria each year for the distribution of Daled Minim, and in most years, one of these esrogim was the one used by the Rebbe.

In 5756 (1996), he moved to [[Eretz Yisroel]] and lived in Beitar Illit and Kfar Chabad. After several years, he returned to the United States and settled in Crown Heights, where he lived until his passing.

He passed away at age 100 on Sunday, 3 Kislev 5780 (2019) as the elder of Chabad chassidim.
