Barend Coenraad Petrus Jansen was born in Zwolle, Netherlands back in 1884.  In 1904, he enrolled at the University of Amsterdam graduating in 1909 with a degree in chemistry.  After graduation, he became an assistant to Professor G. van Rijnberk at the Physiology Department of Amsterdam University. 

While he worked for Professor Rijnberk he became interested in biochemistry.  In 1913, he became Doctor of Chemistry at the University of Utrecht.  Later he was the head of the Physiological Chemistry in Amsterdam.  He moved on to be the head of the Department of Pharmacy and Chemistry at the Medical Laboratory in Java.  He died in 1962, he was 78.

What you may not know about Barend is that in 1926 he isolated in crystalline form the first vitamin to be obtained in pure form, that vitamin was B1.

Hmm, I am not even sure what B1 is but it appears that it is contained in all of those healthy foods that Barbara Todaro shared with us so I will eat more of those foods!

I think that started a whole new round of vitamin production.

Good morning, James... Vitamin B is a very important vitamin and I take it in copious amounts. Now I know whom to thank for it.

Hello James - Mr Jansen's name is certainly one of those "more-than-a-mouthful" moments that may be difficult to pronounce but his work certainly resulted in a wealth of necessary discoveries.

James Dray I had a great chemistry set when I was a kid and I think with a little encouragement I may have pursued a education in it and gone beyond that. To bad my folks say it as a toy and a way to keep me out of their hair for a few hours.

My ex-wife grew up near Zwolle and I have visited it several times, got to say the Dutch are a clever and industrious bunch.

Dear James,

Sounds like an interesting guy, who studied something we are still profiting from.

Chemistry was not a subject that I enjoyed in high school. It is was up to me, B1 would have remained undiscovered. Thanks to Mr. Jansen, we can enjoy its benefits.
