I'm going to throw a few wild cards in - the NPOV needs to be considered carefully. Jan Baptiste van Helmont actually lived at Neder-over-Heembeek, in a farm in the middle of what is now an industrial zone halfway between Brussels and Vilvoorde, close to the church of St Peter and St Paul. In the mid-1840s, the farm was certainly the residence of Count Gioacchino Pecci, Papal Nuncio to Belgium and future Pope Leo XIII, who is reported to have conducted an extensive search of the property for traces of the reported alchemical workings. Mercurius van Helmont is said to have reported that his father, having graduated as a doctor of medecine in the Paracelsian school, was visited by the French Baron René de Cerclairs in 1618. The two talked late into the night, and de Cerclairs left an alchemical powder which van Helmont then used to transmute mercury into gold (apparently the subject of a formal experimental report). This needs full checking, a copy of Mercurius' text would be much appreciated. Mercurius, born later that year, was named for the event, and went on to become one of Leibnitz' tutors in Berlin - Leibnitz wrote his epitaph. De Cerclairs is interesting as independant evidence suggests not only that he was extraordinarily long-lived, but had previously succeeded in extensive alchemical transmutations. This success then triggered van Helmont's interest in assessing chemical reactions objectively, and thence was born one of the axes of scientific rigour. - jelmain Brussels 03:11, 28 December 2006 (UTC)
There should be a disambiguation page for Jan van Helmont. Jan van Helmont was a Flemish physician and alchemist in the early 1600's who was one of the first experimenters to study plant metabolism. He grew willow trees and studied their growth, and after meticulous measuring of all the soil and water involved with his growing plants, he [mistakenly] concluded that plants acquire their mass from the water given to them. - Rlee1185 04:36, 18 June 2005 (UTC)
I just now reverted van Helmont's year of birth to 1577, the year in the article's first line and in three of the four "External links" on the page. I've also seen the year 1579 in a few sources. Does anyone know why there are two different years in print? Is it perhaps due to a calendar change? -- Astrochemist 23:54, 3 October 2007 (UTC)
This article is an interesting one, but my expertise is not in this particular area and my contributions have been copyediting, and vandal chasing. In the future I will leave the article to other editors. Best wishes to all. - Astrochemist ( talk) 13:33, 17 September 2008 (UTC)
When exactly was the tree experiment, and was he prosecuted for it?
Also, is there a source for detail regarding:?

Dutch surnames are spelled with capitals when there is no first name mentioned. In this case 'Jan Baptist van Helmont' or 'Van Helmont'. — Preceding unsigned comment added by 83.86.90.39 ( talk) 23:08, 21 September 2017 (UTC)
