Justus von Liebig

Justus Freiherr von Liebig (12 May 1803 – 18 April 1873) was a German chemist who made major contributions to agricultural and biological chemistry, and was considered the founder of organic chemistry. As a professor at the University of Giessen, he devised the modern laboratory-oriented teaching method, and for such innovations, he is regarded one of the greatest chemistry teachers of all time. He has been described as the "father of the fertilizer industry" for his emphasis on nitrogen and certain minerals as essential plant nutrients, and his formulation of the Law of the Minimum which described the effect of individual nutrients on crops. He also developed a manufacturing process for beef extracts, and founded a company, Liebig Extract of Meat Company, that later trademarked the Oxo brand beef bouillon cube.

Early life and education

Justus von Liebig was born in Darmstadt into the middle-class family of Johann Georg Liebig and Maria Caroline Möser in early May 1803. His father was a drysalter and hardware merchant who compounded and sold paints, varnishes and pigments, which he developed in his own workshop. From childhood Justus was fascinated with chemistry.

Liebig (crater)

Liebig is a lunar crater that is located to the south-southeast of the crater Mersenius, and west of the Mare Humorum in the southwest part of the Moon. To the southwest of Liebig is the slightly smaller crater de Gasparis.

The rim of Liebig has a low inner wall, with an interior floor that is nearly featureless except for a few tiny craterlets. It is nearly, but not quite circular, with outward bulges to the west and southeast. The small, cup-shaped crater Liebig A lies along the inner wall and part of the interior floor.

The western edge of the Mare Humorum is a fault line designated the Rupes Liebig, named after this crater. This fault extends for about 180 km along the shore. To the southwest, in the section of lava-flooded surface between Liebig and de Gasparis, is a system of rilles named the Rimae de Gasparis. These cover an area with a diameter of 130 km.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Liebig.
