Chryssa's first solo exhibition

An equally important bond between Chryssa and Martin, and one they shared with Tawney, was the challenge of succeeding as a woman in an art world dominated by men.

Chryssa, artist who saw neons potential as a medium, dies at 79 (New York Times obituary)

In 1961, the Guggenheim Museum presented a solo exhibition of Chryssa's work, a remarkable honor for a twenty-eight-year-old. Meanwhile, she had begun using neon in her sculpture, sometimes incorporating rheostats so viewers could control the electric current; in these works, letters and words became something more than linguistic elements. From 1964 to 1966 she constructed a gigantic assemblage that she called The Gates to Times Square. Two huge letter As form the "gates" to a gleaming block of stainless steel and Plexiglas that seems to quiver in the play of pale blue neon light.
