Angelina Beloff was born in Saint Petersburg, Russia on June 23, 1879 and raised there by an intellectual family.

During this time, her talent developed, learning engraving work in wood and metal and she earned recognition for her painting and drawing.
She also worked as an art teacher.

Thus Paris attracted artists from various countries.
She met a number of Mexican artists in France and Belgium, meeting Diego Rivera during a trip with artist Marie Blanchard to Brussels.
Rivera pursued her romantically and were married in Paris in 1909.
They had one child named Miguel Ángel, who died of lung complications when he was only fourteen months old.
