He represented the ministry with Georg Leibbrandt in the January 1942 Wannsee Conference, at which the genocidal Final Solution to the Jewish Question was planned.

After one term in Lausanne, he unexpectedly received an appointment as a Fahnenjunker (cadet officer) with the 68th (6th Rhenish) Infantry Regiment in Koblenz in 1912.

[2] During World War I he fought with Infantry Regiment 363 on the Western Front, earning the Iron Cross first and second class and the Wound Badge.

[3] In September 1930, Meyer was elected to the Reichstag from electoral constituency 17, North Westphalia, and on 31 January 1931, he was appointed the Nazi Party Gauleiter of the newly-formed Gau Westphalia-North.

Finally, on 4 November 1938 he was made Oberpräsident of the Prussian Province of Westphalia, thus uniting under his control the highest party and governmental offices in his jurisdictions.

On 29 May 1940 he was appointed Acting Reich Defense Commissioner for Military District VI during the absence in Norway of Josef Terboven.

On 17 July 1941 he was named Ständiger Stellvertreter (permanent deputy) to Reichsminister Alfred Rosenberg in the newly-established Reich Ministry for the Occupied Eastern Territories (RMO).

The official minutes of the conference indicate that Myer and Josef Bühler, the representative of the General Government, both expressed the opinion that preparatory measures for the Final Solution should be carried out immediately in their respective jurisdictions.

Nine days after the conference, Myer convened a meeting at the RMO office for representatives of several other ministries and the armed forces high command (OKW).

Myer wrote a letter on 16 July 1942 proposing that a request be addressed to Hitler urging that a decision be made on the Mischlinge question.

He made plans to construct a "Westphalia Wall" to serve as a defensive position but the Allied assault proved unstoppable, and Münster fell to the combined British and American forces on 3 April 1945.
