Ms Wilson said that despite Church's pioneering work, there were very few female artistic directors.
"It's still quite a male-dominated industry," she said.
"I think we should be celebrating, but also asking more women to be involved.
"While there's a a lot of women on the stage, there's not a lot of women backstage, there are not a lot of women technicians, producers, and theatre managers.
"I think that's a real shame."
Among those mentored by Church during her time in Bradford was The Omen actress Billie Whitelaw.
Other actors including Lord Peter Wimsey star Edward Petherbridge, Secret Army actor Bernard Hepton and theatre actor Sir Robert Stephens were also mentored by Church.
She died in 1972 at the age of 79.
Her great nephew, Bruce Durham, said: "Growing up with Esmé around, it was always wonderful to see and hear about her work – whether it was entertaining troops in France during the World War One, becoming the head of The Old Vic Theatre School, or travelling to and from New York."
He said it was "an honour" to see the plaque unveiled.
Lord Neil Mendoza, chairman of Historic England, said: "Esmé Church was a formidable force in British theatre - an actor, director, and teacher whose influence shaped generations of performers.
"Like so many trailblazing women working in the 1920s and 1930s, her legacy has not received the national recognition it deserves."
The plaque reads: "Esme Church, 1893-1972, actress and director ran the Northern Theatre School here."
