Hans Christian Lyngbye (29 June 1782 – 18 May 1837) was a Danish priest and botanist, specialising in algae.
He attended the Latin school in Aalborg until 1802 when he took as his tutor a priest on the island of Vendsyssel.
He then worked with the botanist Niels Hofman Bang which awoke his interest in algae.
He won a competition set by the University of Copenhagen and as a result, Hornemann paid for the printing of his work on algae, Tentamen Hydrophytologiæ Danica, which was published in 1819.
[2] In 1836, he wrote a dissertation for a doctorate degree, but it remained forgotten in the pocket of the cloak worn by the messenger conveying it to the University of Copenhagen and it missed the deadline.
