The history of the cosmological constant and the Lemaître models is reviewed briefly. Using recent cosmological observations, it is found that the cosmological constant if non-zero must be in absolute value less than 2 × 10-56 cm-2. The predictions of the Lemaître models are compared with modern observations. It is shown that Lemaître models without evolution fail to reproduce the observed radio source counts. The existence of quasars with large redshift (z > 2.5) is shown to be strong evidence against the Lemaître models.
