In 1968 (10 November), Lovelace and his collaborators discovered period \(P\approx 33\) ms of the Crab Pulsar.[1][2] As a graduate student working at Arecibo Observatory, Lovelace developed a version of the Fast Fourier transform program [3] which was adapted to run on the Arecibo Observatory's CDC 3200 computer [4]. This program helped to separate the periodic pulsar signal from the noise, and one night he discovered the period of the Crab pulsar, which is approximately 33 ms. [5][6] A month earlier, observers from Jordell Bank Observatory reported a possible presence of two pulsars in Crab Nebula, with a possible period of 1 second [7]. A few days later, Lovelace and collaborators found that only one pulsar is present (the NP ...Crab Pulsar), and estimated its period with a high precision: 33.09 ms. They also found the position of the pulsar on the sky with a high precision of 10'.
