It was Heinz Guderian (Hurrying Heinz) who wrote the German book on motorised warfare in his book Atchung Panzer! (Danger Panzer!).
Rommel wrote the book on the use of infantry in his book Infantry At War.
He was also known for combining infantry and armor better than his contemporaries.
Except for Patton.
Rommel was never a member of the Nazi party, although there is much confusion about that because Goebbels' propaganda machine put out a mostly fictional bio saying he was.
Rommel was for a time an officer in Hitler's personal bodyguard and became one of his favorite generals. That helped him get an early promotion to General and a plum assignment to command one of the Panzer Divisions in the invasion of France, which he could see was the Next Big Thing. Rommel was known for daring infantry tactics and took well to panzer tactics.
The idea to invade France through the Ardennes was Manstein's but Rommel's execution was outstanding.
Rommel's relations with Hitler turned icy during the Battle of Normandy when he and Rundstedt repeatedly requested permission to use active defense tactics, strategic withdrawals and counterattacks. Hitler refused to allow any retreat, forcing them into the war of attrition that ultimately broke their army.
Rommel was not part of the generals' plot. He was, however, friendly with some who were disaffected with Hitler and with some of the conspirators. That was enough for Hitler, who allowed his favorite general to commit suicide and have a hero's funeral, rather than the piano wire hangings he meted out to the conspirators.
Rommel's son became an officer in the Bundeswehr, was pro-Western and an ardent small-d democrat.
