Isaac Habrecht II (1589–1633) was a professor of astronomy and mathematics in Strasbourg.
He was also a doctor of medicine and philosophy.
Isaac Habrecht II made a celestial globe[1] and a couple of celestial planispheres.
[2] He included constellations that were created by Dutch cartographer, Plancius, and he invented the now obsolete constellation Rhombus.
Lacaille's southern star chart of 1756 reconfigured the constellation into le Reticule Romboide (now Reticulum).
