Marie Pasteur (1855) Malerei von Jean-Baptiste Auguste Leloir

One of 3 paintings so far known to depicting Marie Pasteur, wife of Louis Pasteur.

We are talking about Louis Pasteur the French scientist from which pasteurization is named from.

The painting is signed by Jean-Baptiste Auguste LELOIR most likely around 1864 or just after. See description.

The painting was acquired in Switzerland and only after some cleaning the artist Leloir's signature was discovered.

It then turned out that a similar painting in size, color and composition was done also by Leloir of the daughter of Louis Pasteur, Cecile Pasteur in 1864.

The painting of Cecile Pasteur is in the possession of the Pasteur Museum in Paris as well as the other two painting so far knowing to depicting Marie Pasteur.

Cicile Pasteur later died of typhus in 1866 being 12 year old, which encouraged Louis Pasteur works on decreases and bacteria going forward.

The painting here of Louis Pasteurs wife Marie Pasteur, must logically have been done by Leloir around the same time or just after he painted Cicile Pasteur.

Marie Pasteur was born in 1826, so she would have been around 38 old when Leloir painted her, which match the peinting here.

Both face, frisure, jewelry and clothes match both fotos and the 2 other painting of here so far known to exist. ( see enclosed pictures)
