Eymard became familiar with the practice of sustained eucharistic worship during a visit to Paris in 1849, when he met with members of the Association of Nocturnal Adorers who had established exposition and perpetual adoration of the Blessed Sacrament at the Basilica of Our Lady of Victories. Eymard, with permission from the Paris bishops, on May 13, 1856, left the Marist order and founded the Congregation of the Blessed Sacrament for men. The first community was established at 114 rue d’Enfer, Paris. In 1858 he, along with Marguerite Guillot, founded the Servants of the Blessed Sacrament, a contemplative congregation for women.
