Yaakov Asher Sinclair

Personal life Sinclair was born in London to David Sinclair, who became involved in the music business in the 1960s. He was known as John through early adulthood, and was educated at St. Anthony’s Preparatory School in Hampstead, then Clifton College and Bristol University.

He is married to a fellow ba'alas teshuva (returnee to Orthodox Judaism) from Buenos Aires. They have ten children. One of their children, Avi, is proprietor of an award-winning pizza restaurant (While Foreigner was later remixed at Atlantic Records' studios, Sinclair retained the production credit on the album's release.)

In 1970, one of Sinclair's photographs appeared on the cover of the British Journal of Photography.

Later, during his rabbinic career as Yaakov Asher Sinclair, he continued publishing new photography and written content, particularly in his book Seasons of the Moon.. However, he remained secular until 1987, when he visited Israel, became enamored of Torah study, and decided to move to Jerusalem. He studied at Yeshiva Ohr Someach and the Mir Yeshiva, both in Jerusalem. He received his rabbinical ordination in 1996.

He became well-known in the Orthodox Jewish community as speaker, holding the plenary or keynote speaker positions at an Agudath Israel convention, and a 2018 Project Inspire event. He regularly lectures in Talmud and philosophy at the Ohr Sameach yeshiva's Tannenbaum College of Jewish Studies.

Sinclair is a photographer and author. His photography book, Seasons of the Moon, is a collector's item, and features his black and white photography, poetry, and essays about the Torah. He has another book on the bible, The Color of Heaven.

Works The Color of Heaven - A collection of Torah lessons and inspirational stories. Seasons of the Moon - A black-and-white photography book combining poetry and Torah essays.
