	Jan Baptist van Helmont Summary
		Van Helmont called this class of vapors by the term "gas." He referred to gas as being "wild," stating that this new type of substance "could not be contained by vessels nor reduced into a visible body." Van Helmont described and identified a variety of gases and therefore is credited as the "discoverer" of gas.
		As van Helmont concluded: "There-fore 164 pounds of wood, bark, and root have arisen from water alone." Van Helmont thus demonstrated that the main source of plant nutrition was not the soil, thus countering a widely held belief among his contemporaries.
		Jan Baptist van Helmont (January 12, 1577–December 30, 1644) was a Flemish chemist, physiologist and physician.

	Jan Baptista van Helmont - Crystalinks
		Jan Baptist van Helmont (January 12, 1577 - December 30, 1644) was a Flemish chemist, physiologist and physician.
		Born into a noble family in Brussels, he was educated at Leuven, and after ranging restlessly from one science to another and finding satisfaction in none, turned to medicine, in which he took his doctor's degree in 1599.
		In addition to the archeus, which he described as "aura vitalis seminum, vitae directrix," Van Helmont had other governing agencies resembling the archeus and not always clearly distinguished from it.

		In 1625 the General inquisition of Spain condemned 27 of Helmont's "propositions" for heresy, impudent arrogance, and association with Lutheran and Calvinist doctrine.
		Helmont's life was virtually free of patronage, undoubtedly because of his personal means.

	Lady Anne Conway (Stanford Encyclopedia of Philosophy)
		It was as a result of a search for relief from this that she came into contact with the Flemish physician and philosopher, Francis Mercury van Helmont, son of the iatrochemist, Jan Baptiste van Helmont.
		It was through Van Helmont that Anne Conway was introduced to kabalistic thought and to Quakerism.
		However, although she was unusual as a female philosopher of the seventeenth century, by virtue of the fact that her philosophy achieved publication, the anonymity of her work has ensured that she has suffered the same neglect that has been the lot of most pre-modern female philosophers.
