If I remember history correctly Tetra-Methyl-Lead was developed prior to WWII for aircraft fuel by the U.S. The desire was to produce higher compression aircraft engines for higher performance. The Germans in fact worried that the Allies had gasoline with lead antiknock compounds and they (the Germans) did not. Given that the Germans did not have leaded gasoline it must not have been widely available prior to the war. Antiknock compounds were not required as long as the compression ratio was held low enough. It was the mid 1950's before compression ratios in autos begin to rise to the level needing leaded gasoline.
