Nicolaus Copernicus published an early heliocentric model that involved perfect circles. The model challenged the traditional geocentric Ptolemaic system and the idea that the Earth is at the center of the universe. Copernicus' heliocentric system was published in his book, "On the Revolutions of Celestial Spheres".
Copernicus published this model after his death in 1543. The first publication was in a Polish language translation of the work by Rheticus in 1617.

Wartime needs increased labor demands for both male and female workers, heightened domestic hardships and responsibilities, and intensified pressures for Americans to conform to social and cultural norms.
