Regrettably, I do not know who was the 1st author of the printf source.
There are many implementations of printf. Google search for "printf source code" returns lots of links, for example:
http://www.menie.org/georges/embedded/index.html#printf
http://www.sparetimelabs.com/tinyprintf/index.html
etc...
You may download GNU clib sources or buy Visual Studio with RTL sources.
Write your own printf (one week, including complete documentation ;))...

Usually the author of the compiler that has the functions defined.

>who wrote the functions printf, scanf .
You mean who "writes" the functions. Generally every new compiler re-implements printf and most or all of the standard library and the author of the compiler does it (or someone on the team if there's more than one programmer).
>what is it's sourcr code?
I'll attach an example implementation of C89's stdio library.
