Project Ozma: The First Systematic Search for Artificial Radio Signals from Nearby Stars (1960)
To the point
Project Ozma was the first systematic search for artificial radio signals from nearby stars, led by Frank Drake at Green Bank, West Virginia, which scanned the 21-centimeter hydrogen line near 1,420 MHz toward Epsilon Eridani and Tau Ceti for about 150 hours in 1960 but detected no signals, yet laid the groundwork for future SETI research.
