This blog is about one of the best known scientists in the history of the world,Jan Ingenhousz.

Jan Ingenhousz or Ingen-Housz  (8 December 1730 – 7 September 1799) was a Dutch physiologist, biologist and chemist.

He is best known for discovering photosynthesis by showing that light is essential to the process by which green plants absorb carbon dioxide and release oxygen. He also discovered that plants, like animals, have cellular respiration.In his lifetime he was known for successfully inoculating the members of the Habsburg family in Vienna against smallpox in 1768 and subsequently being the private counsellor and personal physician to the Austrian Empress Maria Theresa.

Okay, lets be fair. He actually wasn’t a well known scientist at all and most of you(including me) probably only saw his name for the first time today, either because of this blog or more likely because Google reminded us of his Birthday today.

Photosynthesis is so essential to life on this planet that it’s easy to forget we didn’t even know about it 250 years ago.

The process of plants converting water and carbon dioxide into sugar and oxygen, using light as a catalyst, was first discovered by Dutch scientist Jan Ingenhousz in 1779.

Ingenhousz began studying medicine at the age of 16, and spent the first part of his career developing a vaccination for smallpox.

In the 1760s he travelled to London and on to Hertfordshire, where he immunised 700 village people in a successful effort to combat an epidemic.

This involved the fairly gruesome process of pricking the skin with a needle that had been dipped into the pus of an infected person’s wound.It worked, however, and after word of Ingenhousz’s success spread, he was invited by the Austrian Empress Maria Theresa to inoculate her entire family.

Over the years, he turned his attention to other scientific pursuits including energy generation, particle motion and gaseous exchange in plants.

Alhough it was already known that plants produced and absorbed gases, it was Ingenhousz who first noticed that oxygen was produced by leaves in sunlight, and carbon dioxide produced in darkness.

This demonstrated that some of the mass of plants comes from the air, and not only the water and nutrients in the soil.

He published his findings in 1779, significantly influencing further research on plant life in the centuries to follow.

Today’s Google doodle focuses on Ingenhousz’s lasting contributions to our understanding of the natural world, on what would have been his 287th birthday.

He died September 7, 1799, Bowood, Wiltshire, England.

Wolfram Sievers-MD of Sick scientists

Wolfram_Sievers

Wolfram Sievers was the Reich Manager of the Ancestral Heritage Society (“Ahnenerbe”) and Director of its Institute for Military Scientific Research (Institut fuer Wehrwissenschaftliche Zweckforschung)

In order to understand how sick and twisted this man and his colleagues were I will demonstrate this not by horrific images but by a letter he send to another ‘sceintist’ Dr Brandt. The letter was used in the trial against Wolfram Sievers during the Doctors’ Trial at Nuremberg following the end of World War II(the picture below shows his ‘comrade’ Dr Barndt, during the trial)

“Subject: Securing of skulls of Jewish-Bolshevik commissars for the purpose of scientific research at the Reich University, Strassburg.

We have a nearly complete collection of skulls of all races and peoples at our disposal. Of the Jewish race, however, only very few specimens of skulls are available, with the result that it is impossible to arrive at precise conclusions from examining them. The war in the east now presents us with the opportunity to overcome this deficiency. By procuring the skulls of the Jewish- Bolshevik commissars, who represent the prototype of the repulsive but characteristic subhuman, we have the chance now to compile good, scientific documents.

The best practical method for obtaining and collecting this skull material could be handled by directing the Wehrmacht to turn over alive all captured Jewish- Bolshevik commissars to the Field Police. They, in turn, are to be given special directives to inform a certain office at regular intervals of the numbers and place of detention of these captured Jews and to give them close attention and care until a special delegate arrives. This special delegate, who will be in charge of securing the material (a junior physician of the Wehrmacht or even the Field Police or a student of medicine equipped with a motor car and driver), will be required to take a previously established series of photographs, make anthropological measurements and, in addition, determine as far as possible other personal data of the prisoners.

Following the subsequently induced death of the Jew, whose head should not be damaged, the physician will separate the head from the body and will forward it to its proper point of destination in an hermetically sealed tin can, especially made for this purpose and filled with a conserving fluid. Having arrived at the laboratory, the comparison tests and anatomical research on the skull, as well as determination of the race membership and of pathological features of the skull form, the form and size of the brain, etc., can proceed by means of photos, measurements and other data supplied on the head, and the skull itself.”

That was the report which you forwarded to Brandt?

A. Yes, that was the report of Professor Hirt.”

It was Hirt who mainly carried out the ‘collecting’ but it was Sievers who was his direct superior and it was his wish to have a collection after the war of a extinct race.

Sievers was sentenced to death on 20 August 1947 for crimes against humanity, and hanged on 2 June 1948, at Landsberg prison in Bavaria.
