Gabrielle Bloch (17 February 1870[1][better source needed] – 14 July 1961), known professionally as Gab Sorère, was a French art promoter, set designer, mechanical innovator, filmmaker and choreographer of the Belle Époque.

When Fuller died, Sorère inherited the dance troupe and laboratory of her partner and strove to keep her legacy as a visual effects artist alive.

[9] During World War I, Bloch established a relief service to transport clothing and food supplies to Belgium and northern France.

[10] She was instrumental in urging Fuller to open a dance school to prevent her rival Isadora Duncan from gaining the upper hand with students.

[23] After Fuller's death, Sorère became the partner of Damia[2] and continued to experiment with phosphorescent salts to achieve theatrical lighting effects.

[26] Four years later, in 1938, Sorère produced Ballets et Lumières with the Mazda company as a tribute to Fuller, using blacklight and fluorescent paint.
