Original Pen-Plotted Artwork

From the Matildas series.

Up close, a dense architectural pattern. Step back, and small
variations resolve into a portrait of Nettie Stevens, embedded
in the structure that erased her.



Nettie Stevens (1861-1912)


She was the first to demonstrate that the Y chromosome determines
sex (1905). Identified the XY system in beetles and flies. 38 papers
in 11 years.

Credit for her discovery went to Edmund Wilson, who published similar
findings the same year but made a smaller theoretical leap.

Her doctoral advisor Thomas Hunt Morgan built his career on the
chromosome theory she had proven, while he himself had resisted it.
He won the 1933 Nobel in Medicine for that foundation. In her
obituary, he called her a great technician, not a theoretician.

In 1906, Wilson and Morgan were invited to speak on sex determination
at a major conference. Stevens was not.
