The four pieces of information in each box of most periodic tables are the element's name, the element's symbol, the element's average atomic weight and the element's atomic number. Other periodic tables have other information, but standard periodic tables almost always have those four.
The two men that are credited with the development of the first periodic tables in 1869 are Dmitri Mendeleev and Lothar Meyer. They produced similar periodic tables independently. Lothar Meyer's table was actually publishes in 1870, a year after Mendeleev.
