Meir Simcha was born in Butrimonys, Lithuania, to Samson Kalonymus, a local wealthy merchant. According to family tradition, his later success in Torah study was attributed to two blessings his parents had received from local rabbis before his birth. He received his education locally, and managed to evade the regular roundups of Jewish boys that were being held as a result of the Cantonist decrees that had been in effect since 1827. After marrying in 1860, at age 17, he settled in Białystok, Poland, where he was supported by his wife, who opened a business to support him while he continued his Talmudic studies. After 23 years there he finally, after turning down many offers, accepted the rabbinate of the mitnagdim in the Latvian town of Dvinsk, now known as Daugavpils. He served in that position for 39 years until his death. In Dvinsk, his counterpart was the Hasidic Rabbi Yosef Rosen, known as the Rogatchover Gaon or by his work Tzofnath Paneach. The two had a great respect for each other, despite Rosen's legendary fiery temper, and on occasions referred questions in Jewish law to each other. They also shared a love for the works of Maimonides. In 1906, a certain Shlomo Friedlander claimed to have discovered and then published two tractates of the Jerusalem Talmud that had been considered to have been lost for hundreds of years. Rabbi Meir Simcha was one of the prominent rabbis who discovered that the work was a very clever forgery, and denounced it as such. In Dvinsk, he received visitors from the whole region, and was frequently consulted on issues affecting the community at large, including Poland and Lithuania. He reputedly turned down offers for the rabbinate in various large cities, including Jerusalem, New York City and Kovno. He died in a hotel in Riga while seeking medical treatment.
Family
Rabbi Meir Simcha of Dvinsk had one unmarried daughter with mental issues who predeceased him. He therefore has no living descendants. As a result of this, one of his most prominent students and a close friend, Rabbi Yisrael Avraham Abba Krieger, committed to carrying on his legacy.

Ideas and influence
He opposed the non-religious Zionist groups,, but was in favor of Religious Zionists. After the Balfour Declaration, he was of the opinion that the Three Oaths were no longer in effect. He was present at the founding meetings of Agudath Yisrael in the German town of Bad Homburg, but could not attend the first large conference in Katowice due to poor health. He had several clashes with some of his contemporaries, including Rabbi Yisrael Meir Kagan on political issues and questions of Jewish law. It is harder to determine his exact stance in philosophical matters, although much can be gleaned from his Meshech Chochma.
