Jack Butler (artist)

[6] The print depicted a flattened female torso and was "indexical as opposed to formal"; Butler wrote that this "allied my work with the development of the conceptual-art movement".

By 1970, the Canadian Eskimo Arts Council approved the sale of a collection of 31 prints and requested a special exhibition for the spring and the program expanded adding two more positions.

"[8] Between 1976 and 1981, Butler was commissioned by the Children's Hospital of Winnipeg Research Foundation to construct models representing the developmental changes that take place during normal genital morphogenesis.

[7] Butler acted as a member of a research team that included urological surgeon Alan Decter, pediatric endocrinologist Jeremy Winter, as well as a radiologist, and a geneticist.

[13] The lack of good structural information led Butler to perform microscopic observations of the developing genitals of aborted fetuses and embryos.

[7] Butler then worked with pediatric respirologist Dr Hans Pasterkamp on models describing the structure of the terminal acinus of the embryological lung.

[citation needed] As final visualizations, in 1981, Butler constructed five physical models in acrylic that describe the development of the tips of the branches of the lung, through embryonic and fetal stages of growth up to birth.
