Friedrich Wilhelm Heinrich Alexander von Humboldt (1769 - 1859) was a German geographer, naturalist, explorer.Humboldt's quantitative work on botanical geography, geology and meteorology formed the foundation for the field of biogeography. Humboldt’s studies also pioneered modern geomagnetic and meteorological monitoring. His world travels also allowed Humboldt to make scientific observations of strata in the countries he visited. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined, especially Africa and South America. Humboldt confirmed the conjecture that English, French and German stratigraphic sequences are fundamentally identical and that the European order of superposition can be found also in North and South America. The original, French edition, “Essai geognostique sur le gisement des roches dans les deux hémisphères also appeared in 1823 as the English edition. The work is very rare.
