[1] Seidel served for most of World War II as the head of German Air Force organization, armament, maintenance, and supply.

He was a practical realist who distanced himself from his idealist boss Hans Jeschonnek, Luftwaffe Chief of Staff, an unquestioning follower of Adolf Hitler.

Seidel attempted to implement the expansive German war plans but suffered from heavy combat losses of materiel and men.

Hans-Georg von Seidel was born in the farming village of Diedersdorf in the county of Lebus, a rural district in the Province of Brandenburg, Kingdom of Prussia, on 11 November 1891.

[1] On 16 April 1938 Seidel was named Generalquartiermeister der Luftwaffe, the top staff officer in charge of supply and administration for the German Air Force, a position he held for the next six years.

Seidel agreed with top airman Hermann Göring and influential General Erhard Milch that their leader was a negative factor in air planning.

[7] In autumn 1940, Seidel was informed by Hermann Göring, leader of the Luftwaffe, of Adolf Hitler's plan to invade the Soviet Union the next summer.

For the 800,000 Luftwaffe personnel on the Eastern Front, Seidel was able to work with Milch to secure extra woollen underwear, fur boots, and other winter wear.

On 23 November, Seidel ordered all German ministry, training, and staff aircraft of any size to join the airlift into Stalingrad.

The Sixth Army needed 700–800 tonnes each day, with food and munitions as top priority, but they received only a fraction of that, and some deliveries such as spices and summer clothing were completely useless to the troops.

[17] Seidel noted the great equipment losses in that theatre: "Of 100,000 Luftwaffe vehicles in the East, only 15 per cent still functioning early in January 1942.

[16] From July 1944 to February 1945 Seidel served in Berlin as commander of Luftflotte 10 (Air Fleet 10), a training and replacement organization.

Late in February he was named leader of the Reserve Luftwaffe High Command, a position he was to hold for a few months until the end of the war.

He was interviewed for his views on the war, and gave his opinion that the invasion of Germany would have failed except for Allied air power disrupting German supply lines.
