While both the ancient Greeks and Romans knew of algae, and the ancient Chinese<ref>Porterfield, William M. (1922) [https://books.google.com/books?hl=en&lr=&id=6J8mBMCygk8C&oi=fnd&pg=PA297 "References to the algae in the Chinese classics"] ''Bulletin of the Torrey Botanical Club'' 49: pp.&nbsp;297&ndash;300</ref> even cultivated certain varieties as food, the scientific study of algae began in the late 18th century with the description and naming of [[Ecklonia maxima|''Fucus maximus'' (now ''Ecklonia maxima'')]] in 1757 by [[Pehr Osbeck]]. This was followed by the descriptive work of scholars such as [[Dawson Turner]] and [[Carl Adolph Agardh]], but it was not until later in the 19th century that efforts were made by [[Jean Vincent Félix Lamouroux|J.V. Lamouroux]] and [[William Henry Harvey]] to create significant groupings within the algae. Harvey has been called "the father of modern phycology"<ref>[http://www.livestrong.com/article/43795-phycology/ "About Phycology"] Lance Armstrong Foundation</ref> in part for his division of the algae into four major divisions based upon their pigmentation.

It was in the late 19th and early 20th century, that phycology became a recognized field of its own.  Men such as [[Friedrich Traugott Kützing]] continued the descriptive work. In Japan, beginning in 1889, [[Kintarô Okamura]] not only provided detailed descriptions of Japanese coastal algae, he also provided comprehensive analysis of their distribution.<ref>Tokida, Jun and Hirose, Hiroyuki (1975) ''Advance of Phycology in Japan'' Junk, The Hague, Netherlands, [https://books.google.com/books?id=ig4yuw_GC_4C&pg=PA241 page 241], {{ISBN|90-6193-026-X}}</ref> Although [[Robert Kaye Greville|R. K. Greville]] published his ''Algae Britannicae'' as early as 1830, it was not until 1902 with the publication of ''A Catalogue of the British Marine Algae''<ref>Batters, Edward Arthur Lionel (1902) ''A catalogue of the British Marine Algae being a list of all the species of seaweeds known to occur on the shores of the British Islands, with the localities where they are found'' Newman, London, {{OCLC|600805992}}, published as a supplement to ''Journal of Botany, British and Foreign''</ref> by Edward Arthur Lionel Batters that the systematic correlation of records, extensive distribution mapping and the development of [[identification key]]s began in earnest.  In 1899–1900, [[Anna Weber-van Bosse|Anna Weber-Van Bosse]], a Dutch Phycologist travelled on the [[Siboga expedition]] and later in 1904, published ''[https://www.biodiversitylibrary.org/item/18871#page/6/mode/1up The Corallinaceae of the Siboga-expedition]''.<ref>{{Cite book|title=The Corallinaceae of the Siboga-expedition|last1=Weber-Van Bosse|first1=A.|last2=Foslie|first2=M.|publisher=F. J. Brill|year=1904}}</ref>

As early as 1803 [[Jean Pierre Étienne Vaucher]] had published on the [[Isogamy|isogamy (sexual conjugation)]] in the algae, but it was in the early 20th century that reproduction and development began to be extensively studied.  The 1935 and 1945 comprehensive volumes of [[Felix Eugen Fritsch]] consolidated what was then known about the morphology and reproduction of the algae. This was followed in the 1950s by the development of area checklists, led by [[Mary Parke]] with her 1931 ''Manx Algae'' and followed in 1953 by her "A preliminary check-list of British marine algae"<ref>Parke, Mary W.
