He was considered instrumental in many of the studies conducted on galaxies. Walter Baade was born in Germany in 1893 and would become one of the most well respected astronomers of his time and in history.

Walter Baade was a teacher and loved widely by those he taught. However, history would show that Baade was worthy of honorable mention for his most innovative work in astronomy.

As a teacher, Baade trained many in the field of astronomy. However, his professional contributions to astronomy included a discovery with involvement of asteroids that would become known as Hidalgo (1920) and Icarus (1948).

Interested in the overall distances between galaxies, Baade was profoundly moved by his discoveries. He wanted to learn all that he could about the population of the galaxies no matter how stellar they seemed.

Dedicated to providing facts, Walter Baade found some discrepancies with the Edwin Hubble theory. He proved without reasonable doubt that Hubble's beliefs about the population elements of Cepheid variables were incorrect. Documenting those differences and developing his own theories, Baade was commended and widely recognized for his achievements in science.

Walter Baade died in 1960. He left behind a legacy to be emulated in astronomy. However, many considered him an observational astronomer rather than one with the ability to utilize astrophysics training. Regardless, Walter Baade's universe was one that he fully explored using any and all tools that he had to guide him into other worlds.
