Ze zijn vernoemd naar de Duitse wiskundige en astronoom Karl Brandan Mollweide, die ze in 1808 publiceerde. De vernoeming is historisch niet correct, aangezien Isaac Newton de formules al een eeuw eerder had gevonden. [1] De formules zijn:

The other parallels compress near the poles, while the other meridians are equally spaced at the equator.
