Nope. As seen from the first hit in google, only a few countries require transit visas in Germany, and none of them are the US.
The list of countries are:
AFGHANISTAN, BANGLADESH, DEMOCRATIC REPUBLIC OF THE CONGO, ERITREA, ETHIOPIA, GHANA, INDIA, IRAN, IRAQ, JORDAN ** (please see below), LEBANON, MYANMAR, MALI, NIGERIA, PAKISTAN, SOMALIA, SRI LANKA, SUDAN, SOUTH SUDAN, SYRIA, TURKEY
although it should be noted that there are other cases for even those countries whereby they may not require one (eg if they have a US visa in their passport - go figure!).

No, US citizens do not need a visa to enter the Schengen area. You may stay for up to 90 days in any 180 day period without a visa.
For further information, see Visa policies in the European Union.
