When was stellar parallax first observed?

Is parallax a star?
The parallax refers to the apparent change in the star's position, due to Earth's movement around the Sun. This parallax can be used to measure the distance to nearby stars (the closer the star, the larger will its parallax be).
What is a parallax bar used for?

Who is the first person to measure the parallax of a star?
The first person to notice and report on stellar parallax was the Italian astronomer, Giuseppe Calandrelli (1749-1827). He reported the parallax for alpha-Lyrae. The first reliable measurement was made, for 61 Cygni, by the German astronomer Friedrich Bessel in 1838.
How is parallax used in computer programming?
