Browning writes that eight of the 15 had doctorates: "Thus it was not a dimwitted crowd unable to grasp what was going to be said to them." Thirty copies of the minutes, known as the Wannsee Protocol, were made. Copy no. 16 was found by American prosecutors in March 1947 in a German Foreign Office folder. Written by Eichmann and stamped "Top Secret", the minutes were written in "euphemistic language" on Heydrich's instructions, according to Eichmann's later testimony. Discussing plans for a "final solution to the Jewish question" (""Endlösung der Judenfrage""), and a "final solution to the Jewish question in Europe" (""Endlösung der europäischen Judenfrage""), the conference was held to share information and responsibility, coordinate efforts and policies (""Parallelisierung der Linienführung""), and ensure that authority rested with Heydrich. There was also discussion about whether to include the German "Mischlinge" (half-Jews). Heydrich told the meeting: "Another possible solution of the problem has now taken the place of emigration, i.e. the evacuation of the Jews to the East, provided that the Fuehrer gives the appropriate approval in advance." He continued:  Under proper guidance, in the course of the Final Solution, the Jews are to be allocated for appropriate labor in the East. Able-bodied Jews, separated according to sex, will be taken in large work columns to these areas for work on roads, in the course of which action doubtless a large portion will be eliminated by natural causes. The possible final remnant will, since it will undoubtedly consist of the most resistant portion, have to be treated accordingly because it is the product of natural selection and would, if released, act as the seed of a new Jewish revival. (See the experience of history.) In the course of the practical execution of the Final Solution, Europe will be combed through from west to east. Germany proper, including the Protectorate of Bohemia and Moravia, will have to be handled first due to the housing problem and additional social and political necessities.The evacuated Jews will first be sent, group by group, to so-called transit ghettos, from which they will be transported to the East. These evacuations were regarded as provisional or "temporary solutions" (""Ausweichmöglichkeiten"").
