The complex was first investigated by John Shae Perring, but it was Gaston Maspero who first entered the pyramid in 1881. Gustave Jéquier was the first to investigate the complex in detail between 1926 and 1936. Jéquier was the first excavator to start actually finding any remains from the tomb reliefs, and he was the first to publish a thorough excavation report on the complex.
