Britain's fourth Astronomer Royal.

Bliss graduated from Pembroke College, Oxford (B.A., 1720; M.A., 1723), and became rector of St. Ebbe's, Oxford, in 1736. He succeeded Edmond Halley as Savilian professor of geometry at the University of Oxford in 1742 and was elected a fellow of the Royal Society the same year. A correspondent and occasional assistant of James Bradley (Bradley, James), third Astronomer Royal, Bliss acted for him in observing the transit of Venus in 1761 and succeeded him as Astronomer Royal in 1762.
