'''Maximilian Franz Joseph Cornelius Wolf''' (21 June 1863 – 3 October 1932) was a German [[astronomer]] and a pioneer in the field of [[astrophotography]]. He was the chairman of astronomy at the [[University of Heidelberg]] and director of the [[Heidelberg-Königstuhl State Observatory]] from 1902 until his death in 1932.

== Early life ==

Max Wolf was born in [[Heidelberg]], Germany on 21 June 1863, the son of medical doctor Franz Wolf. His father encouraged an interest in science and built an observatory for his son in the garden of the family home. It is from here that Wolf was credited with his first astronomical discovery, comet [[14P/Wolf]], in 1884.<ref name=observ>{{cite journal

| pages=355–359  | date=1932 | bibcode= 1932Obs....55..355M}}</ref>

== Life at the university ==

Wolf attended his local university and, in 1888, at the age of 25, was awarded a [[Doctor of Philosophy|Ph.D.]] by the [[University of Heidelberg]]. He spent one year of post-graduate study in Stockholm, the only significant time he would spend outside of Heidelberg in his life. He returned to the [[University of Heidelberg]] and accepted the position of ''privat-docent'' in 1890. A popular lecturer in astronomy, he declined offers of positions from other institutions. In 1902 he was appointed Chair of Astronomy and Director of the new [[Landessternwarte Heidelberg-Königstuhl]] observatory, positions he would hold until his death in 1932.<ref>{{cite journal

While the new observatory was being built, Wolf was appointed to supervise the construction and outfitting of the [[astrophysics]] half of the observatory. He proved to be not only a capable supervisor but also a successful fundraiser. When sent to America to study the construction of the large new telescopes being built there, he returned not only with telescope plans but also with a grant of $10,000 from the American philanthropist [[Catherine Wolfe Bruce]]. Wolf immediately designed and ordered a double [[refractor telescope]] from American astronomer and instrument builder [[John Brashear]]. This instrument, known as the ''Bruce double-[[astrograph]]'', with parallel {{convert|16|in|cm|abbr=on}} lenses and a fast f/5 [[focal ratio]], became the observatory's primary research telescope. Wolf also raised money for a {{convert|28|in|cm|abbr=on}} [[reflector telescope]], the first for the observatory, used for spectroscopy.<ref name=bruce>{{cite journal

In 1910, Wolf proposed to the [[Carl Zeiss AG|Carl Zeiss]] optics firm the creation of a new instrument which would become known as the [[planetarium]]. [[World War I]] intervened before the invention could be developed, but the [[Carl Zeiss AG|Carl Zeiss]] company resumed this project after peace was restored. The first official public showing was at the [[Deutsches Museum]] in [[Munich, Germany]] on 21 October 1923.<ref name="twothousand">

During his trip to America, Wolf was interested in learning more about the relatively new field of [[astrophotography]]. He met the American astronomer and astrophotographer [[E.E. Barnard]], and the two became lifelong correspondents, competitors, collaborators and friends. Wolf wrote a long obituary for Barnard upon his death in 1923.<ref>{{ cite journal | title=Anzeige des Todes von Edward Emerson Barnard | author=Wolf, M.

== Later life and death ==

Heidelberg University became well known for astronomy under Wolf's leadership. Wolf himself was an active researcher, contributing numerous papers in many areas of astronomy up to the end of his life. He died in Heidelberg on 3 October 1932, at the age of 69. He was survived by his wife and three sons.<ref name=observ/>

== Comets and novae ==

Wolf started his career as a comet hunter and continued to discover them throughout his life. He discovered or co-discovered several [[comet]]s, including [[14P/Wolf]] and [[43P/Wolf-Harrington]]. Wolf won a competition with [[E. E. Barnard]] on who would be the first to observe the return of [[Halley's Comet]] (P1/Halley) in April 1910.<ref name=bruce />

He discovered [[EL Aquilae|Nova Aquilae 1927]], a classical nova.

He discovered or co-discovered four supernovae: [[NGC_4424#Supernovae|SN 1895A]] (a.k.a. VW Vir), [[Pinwheel_Galaxy#Supernovae_and_luminous_red_nova|SN 1909A]] (a.k.a. SS UMa), [[NGC_2608#Supernovae|SN 1920A]], and, with [[Karl Wilhelm Reinmuth|Reinmuth]], [[Messier_61#Supernovae|SN 1926A]].

== Dark nebulae ==

One of the many significant contributions Wolf made was in the determination of the nature of ''[[dark nebula]]e''. These areas of the sky, thought since [[William Herschel|William Herschel's]] time to be "holes in the sky", were a puzzle to astronomers of the time. In collaboration with [[E. E. Barnard]], Wolf proved, by careful photographic analysis, that ''dark nebulae'' were huge clouds of fine opaque dust.<ref name=bruce />

== Star catalog ==

Along with E. E. Barnard, Wolf applied [[astrophotography]] to the observation of stars. The ''Bruce double-astrograph'' was originally designed to hunt dim asteroids but it was found to be ideally suited for the study of the [[proper motion]] of low-luminosity stars using much the same technique. In 1919 Wolf published a catalog of the locations of over one thousand stars along with their measured [[proper motion]]. These stars are still commonly identified by his name and catalog number.<ref>{{cite journal | last=Wolf | first=M.

| doi=10.1002/asna.19172042002}}</ref> He continued to add [[proper motion]] star discoveries to this catalog throughout his life, with the catalog eventually totaling over 1500 stars, many more than all of his competitors combined.<ref>{{cite web

The methods used by [[E. E. Barnard]] and Wolf were continued by [[Frank Elmore Ross]] and [[George Van Biesbroeck]] through the mid-20th century. Since that time, photographic plates have been gradually replaced with more sensitive electronic [[photodetectors]] for [[astronomical survey]]s.{{cn|date=June 2019}}

== Asteroids ==
{{see also|Category:Discoveries by Max Wolf}}

In 1891, Wolf discovered his first asteroid, [[323 Brucia]], and named it after [[Catherine Wolfe Bruce]].<ref>{{cite book

Among his many discoveries was [[588 Achilles]] (the first [[Trojan asteroid]]) in 1906, as well as two other Trojans: [[659 Nestor]] and [[884 Priamus]].<ref>{{cite journal |last=Nicholson |first=Seth B. |title=The Trojan asteroids |date=1961 |journal=Astronomical Society of the Pacific Leaflets |volume=8 |issue=381 |pages=239–46 |bibcode=1961ASPL....8..239N}}</ref> He also discovered [[887 Alinda]] in 1918, which is now recognized as an Earth-crossing [[Amor asteroid]] (or sometimes classified as the namesake of its own [[Alinda family]]).<ref>{{cite book

Minor planet [[1152 Pawona]] is named after both [[Johann Palisa]] and Max Wolf, in recognition of their cooperation. The name was proposed by Swedish astronomer Bror Ansgar Asplind. ''Pawona'' is a combination of "Palisa" and "Wolf" (Pa, Wo) joined with a Latin feminine suffix.<ref>{{cite book  |last       = Schmadel | first = Lutz D.  |title = Dictionary of Minor Planet Names |publisher  = Springer Berlin Heidelberg  |page  = 97  |date  = 2007  |doi       = 10.1007/978-3-540-29925-7_1153 |chapter       = (1152) Pawona |isbn       = 978-3-540-00238-3 }}</ref>
