No, he is the former president of the European Parliament. Also the German system is very different from the US and the chancellor is the most powerful political position in Germany, but not the equivalent to the US president.
The president of Germany would be more like the Queen in the UK: head of state with mainly ceremonial powers, but doesn't take much of a roll in actually running the country.
The chancellor was originally a subordinate position to the King of Prussia and later the German Kaiser. After 1918, the Kaiser was replaced by the president, who had a much more diminished role than the Kaiser did, and the chancellor undisputedly became the most powerful position.
In the US, the president is both of those positions rolled into one, with the exception of being elected by the states rather than by Congress.
Fortunately the German president makes his own speeches. https://en.wikipedia.org/wiki/Speech_from_the_throne
Luckily Germany is no longer a monarchy, since 1918.
