History
- The Platonic solids date back to the classical Greeks and were studied by Plato, Theaetetus and Euclid.
- Johannes Kepler (1571–1630) was the first to publish the complete list of Archimedean solids after the original work of Archimedes was lost.
Regular star polyhedra:
- Kepler (1619) discovered two of the regular Kepler–Poinsot polyhedra and Louis Poinsot (1809) discovered the other two.
Other 53 nonregular star polyhedra:
- Of the remaining 53, Albert Badoureau (1881) discovered 36. Edmund Hess (1878) discovered 2 more and Pitsch (1881) independently discovered 18, of which 15 had not previously been discovered.
- The geometer H.S.M. Coxeter discovered the remaining twelve in collaboration with J. C. P. Miller (1930–1932) but did not publish. M.S. and H.C. Longuet-Higgins and independently discovered 11 of these.
- Coxeter, Longuet-Higgins & Miller (1954) published the list of uniform polyhedra.
- Sopov (1970) proved their conjecture that the list was complete.
- In 1974, Magnus Wenninger published his book Polyhedron models, which lists all 75 nonprismatic uniform polyhedra, with many previously unpublished names given to them by Norman Johnson.
- Skilling (1975) independently proved the completeness, and showed that if the definition of uniform polyhedron is relaxed to allow edges to coincide then there is just one extra possibility.
- In 1993, Zvi Har'El produced a complete kaleidoscopic construction of the uniform polyhedra and duals with a computer program called Kaleido, and summarized in a paper Uniform Solution for Uniform Polyhedra, counting figures 1-80.
- Also in 1993, R. Mäder ported this Kaleido solution to Mathematica with a slightly different indexing system.
- In 2002 Peter W. Messer discovered a minimal set of closed-form expressions for determining the main combinatorial and metrical quantities of any uniform polyhedron (and its dual) given only its Wythoff symbol.

Famous quotes containing the word history:
“There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
—Karl Marx (18181883)
“The whole history of civilisation is strewn with creeds and institutions which were invaluable at first, and deadly afterwards.”
—Walter Bagehot (18261877)
“The myth of independence from the mother is abandoned in mid- life as women learn new routes around the motherboth the mother without and the mother within. A mid-life daughter may reengage with a mother or put new controls on care and set limits to love. But whatever she does, her childs history is never finished.”
—Terri Apter (20th century)
