replies: text: Why is there nothing about Jan Baptist van Helmont and his theory on spontaneous generation?  It is his name that is mentioned several times in the address delivered by Louis Pasteur at the "Sorbonne Scientific Soiree" of April 7, 1864.  There needs to be more information on the "experiments" he conducted on the subject. - 168.216.63.73 17:23, 8 March 2005 (UTC)
replies: text:  Please feel free to add it. I'm pursuing an academic path to prove the case, but that will take some time, as it has to be built on the foundations of mediaeval creed. For the record, an initial pointer is to examine the alchemical practices of Phillip II of Spain in Brussels and the Escorial - see René Taylor's contribution to the Wittkower 65th birthday essays, in the book on Architecture - her subsequent independant publication goes further in establishing a background to Cerclairs' activities.Jel 08:22, 20 September 2007 (UTC)

message: 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)
replies: text:  Nonsense! The plant experiment is the most famous experiment of Jan Baptist van Helmont. - Siffler 15:08, 18 February 2007 (UTC)

message: 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)
replies: text: If this ever comes up again, Walter Pagel (who is considered the definitive Van Helmont scholar), frequently cites his birth as January 12, 1579. See: Pagel, Walter, Joan Baptista Van Helmont: Reformer of Science and Medicine (Cambridge: Cambridge University Press, 1982), p. 2.207.237.208.153 (talk) 15:09, 8 August 2012 (UTC)
replies: text: I don't think that the issue here is Julian versus Gregorian calendar.  It is that in 1579-80, many still regarded the year to begin in March, which would make January part of the old year, 1579, in old style, and part of the new new year, 1580, in the new style.Ajrocke (talk) 13:24, 8 September 2014 (UTC)

message: When exactly was the tree experiment, and was he prosecuted for it?
:In 1634 Jean Baptist Van Helmont was arrested for the crime of studying plants and other phenomena. He considered the question "how do plants grow?". The contempory theory was that plants grew by eating soil. He devised an investigation to test the idea. - BBC 
Also, is there a source for detail regarding:?
:... influenced heavily by mystic Paracelsan views. [Jan van Helmont] claimed to have seen and used the philosopher's stone. - E. Weisstein

message: 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)
