Catherine de Hueck Doherty (née Ekaterina Fyodorovna Kolyschkina; August 15, 1896 – December 14, 1985) was a Russian-born Catholic activist who founded the Madonna House Apostolate in 1947.

In 1947, Catherine and her second husband, Irish American journalist Eddie Doherty, moved to the village of Combermere, Ontario, where the Madonna House Apostolate, a Catholic community of laymen, laywomen, and priests, developed and flourished.

[6] Shortly before the turn of the century, Catherine was born in Nizhni Novgorod, Russia, to Theodore (Fyodor) and Emma (Thomson) Kolyschkine.

[9] The family returned to St. Petersburg in 1910, and two years later, at the age of 15, Catherine married her first cousin, Baron Boris de Hueck (1889-1947).

Newly prosperous but with her marriage in ruins, and dissatisfied with a life of material comfort, de Hueck began to feel the promptings of a deeper call through a passage that leaped to her eyes each time she opened the Bible: "Arise—go... sell all you possess... take up your cross and follow Me."

She begged food and clothing, organized activities for the youth, and countered Communist propaganda with the social encyclicals of the popes.

John Lafarge SJ,[12] Catherine initiated an interracial apostolate in Harlem, New York, living with and serving the African-American population.

Catherine's marriage to Baron Boris de Hueck was one of suffering caused by his emotional abuse and continual, flagrant infidelities.

They took vows of poverty, chastity, and obedience in 1955, and on August 15, 1969, in Nazareth, Israel, Eddie was ordained a priest in the Melkite Greek Catholic Church by Archbishop Joseph Raya.

Catherine's marriage and her broader vision of the apostolate were sources of painful disagreement between the Friendship House staff and its foundress.

The community grew into an apostolic family of laymen, laywomen, and priests, breathing from the "two lungs," East and West, of the Catholic Church[15] and offering a vision of the gospel lived out in everyday life.

In 2022 the Madonna House Apostolate numbered over 200 members, with foundations in Canada and the United States, Europe, Russia, and the West Indies.
