He tells you his story…

 

Pierre Bayen

“Hello,

My name is Pierre Bayen, I was born in Châlons-en-Champagne on Febrary 7th 1725, I study pharmacy in Reims then in Paris before starting a military career during the Minorque expedition. I am very helpfull there, as I am considered like the manager of the military pharmacy’s cabinet that I have served for 42 years.

I give a lot of my time to my chemistry works and I am a succesful apothecary candidate and college member 1766.

In april 1774, I found out that the heat of the mercury oxide produces a gaz release and a mass loss. I collect this gaz and notice that it is slighlty denser (thicker) than the air. However, I do not read into my results.

A few months later, the British Joseph Priestley realises the same experience and publishes his results. Lavoisier whom knew about my works meets with Priestley and 7 months later, duplicates our works and he realises that the dephlogistic air was a new element that would allow the combustion. Oxygen was born. I realise at that moment my mistake for not publishing my results , I try unsucessfully to prouve paternity of that discovery, but it is too late.

I am elected member of the Science Academy and named member of the institut since its creation in 1795 until I become General Inspector of the Heath service in 1796. I die in Paris in 1798.”
