It was Lowell
Neptune and Pluto are two heavenly bodies that were predicted to exist before they were sighted. Neptune's existence was predicted based on perturbations in the orbit of Uranus, while Pluto's existence was predicted based on gravitational influences on the orbits of Neptune and Uranus.
Pluto was discovered on February 18, 1930, by astronomer Clyde Tombaugh at the Lowell Observatory in Arizona. The existence of Pluto was inferred based on irregularities in the orbits of Neptune and Uranus, leading astronomers to hypothesize the presence of a ninth planet. Tombaugh's systematic search for a trans-Neptunian object ultimately confirmed Pluto's existence through direct observation.
Both Pluto and Neptune were discovered by observing deviations in the movement of other planets from what they were calculated to be, and from that calculating where something else should be that was causing those deviations.
Pluto was discovered on February 18, 1930 by Clyde Tombaugh at Lowell Observatory in Flagstaff, Arizona. It was discovered using two photographic plates taken of the same place in the sky on January 23 and 29.
The search for Pluto was organized by the Lowell Observatory in Flagstaff, Arizona. Percival Lowell, the founder of the observatory, initiated the search in the early 20th century to find a ninth planet beyond Neptune based on the perceived gravitational influence on Uranus and Neptune. The search ultimately led to the discovery of Pluto by Clyde Tombaugh in 1930.

An American astronomer named Clyde Tombaugh discovered Pluto in 1930
Pluto was discovered in 1930 by the astronomer Clyde Tombaugh. The existence of Pluto was predicted by perturbations of the orbit of Neptune late in the 19th century. Percival Lowell looked for it, and did photograph Pluto in 1915, but didn't recognize what he had seen. The task of finding the planet was given to Clyde W. Tombaugh at Lowell Observatory in Arizona. He did a very careful sky survey which identified Pluto in photos taken on February 18, 1930 and announced it on March 13, 1930
Clyde William Tombaugh was the American astronomer that discovered Pluto!
I believe the name is Percival Lowell.

Pluto was discovered by the American Clyde W. Tombaugh, but it is no longer a planet.
Pluto was discovered on February 18, 1930 by Clyde Tombaugh at Lowell Observatory in Flagstaff, Arizona. It was discovered using two photographic plates taken of the same place in the sky on January 23 and 29.
Pluto was first observed by the astronomer Percival Lowell.
Clyde William Tombaugh was the one who actually first observed the planet pluto, but nobody actually "predicted" that another planet existed. He also discovered what was later called the Kuiper belt.
