Who named stars by assigning them to constellations?

These are different questions. The constellations were created from the imaginations of the people who observed the stars. Most of our "standard" northern hemisphere constellations were from Greek or Roman mythology.

Many of the southern hemisphere constellations were named by European sailors and navigators as they first sailed into southern waters. Note the nautical themed constellation names like "Sextans" and "Telescopium" and "Cetus", the whale.

The International Astronomical Union standardized all of the constellations, and assigned every visible star to one, and ONLY one, constellation.
