Editing Thomas Robert Malthus (section)

== Travel and further career ==
In 1799, Malthus made a European tour with [[William Otter]], a close college friend, travelling part of the way with [[Edward Daniel Clarke]] and [[John Marten Cripps]], visiting Germany, Scandinavia and Russia. Malthus used the tour to gather population data. Otter later wrote a ''Memoir'' of Malthus for the second (1836) edition of his ''Principles of Political Economy''.<ref>{{cite DNB|wstitle=Otter, William|volume=42}}</ref><ref>{{cite ODNB|id=20935|title=Otter, William|first=Arthur|last=Burns}}</ref> During the [[Peace of Amiens]] of 1802 he travelled to France and Switzerland, in a party that included his relation and future wife Harriet.<ref>{{cite book|first1=Jean-Antoine-Nicolas|last1=de Caritat Condorcet (marquès de)|author-link1=Marquis de Condorcet|first2=William|last2=Godwin|author-link2=William Godwin|first3=Thomas Robert|last3=Malthus|editor-first=John|editor-last=Avery|title=Progress, Poverty and Population: Re-Reading Condorcet, Godwin and Malthus|url=https://books.google.com/books?id=ZA0lNlvbh0sC&pg=PA64|date=1997|publisher=[[Routledge]]|location=Abingdon, England|isbn=978-0-7146-4750-0|page=64}}</ref>

In 1803, he became rector of [[Walesby, Lincolnshire]].<ref name="ReferenceA"/>

In 1805, Malthus became Professor of History and Political Economy at the [[East India Company College]] in [[Hertfordshire]].<ref>Malthus T. R. 1798. ''The Essay of the Population Principle''. Oxford World's Classics reprint: xxix, Chronology.</ref> His students affectionately referred to him as "Pop", "Population", or "web-toe" Malthus.

Near the end of 1817, the proposed appointment of [[Graves Champney Haughton]] to the college was made a pretext by Randle Jackson and [[Joseph Hume]] to launch an attempt to close it down. Malthus wrote a pamphlet defending the college, which was reprieved by the East India Company within the same year, 1817.<ref>{{cite book|author=Thomas Robert Malthus|title=T.R.

In 1818, Malthus became a Fellow of the [[Royal Society]].
