In 1968 (10 November), Lovelace discovered period \(P\approx 33\) ms of the Crab Pulsar.[1][2][3] As a graduate student working at Arecibo Observatory, Lovelace developed a version of the Fast Fourier transform program [4] which was adapted to run on the Arecibo Observatory's CDC 3200 computer [5]. This program helped to separate the periodic pulsar signal from the noise, and one night he discovered the period of the Crab pulsar, with a high precision, 33.09 ms, and its position on the sky with precision of 10'.[2][6]
