==History==
Delta Sigma Pi  was established on {{dts|1907|11|07}} at [[New York University Stern School of Business|New York University's School of Commerce, Accounts and Finance]]. Its founders were:
* Alexander F. Makay
* H. Albert Tienken
* Harold V. Jacobs
* Alfred Moysello<ref name="Baird's">{{cite book |editor1-first=Jack L. |editor1-last=Anson |editor2-first=Robert F. |editor2-last=Marchenasi |title=Baird's Manual of American Fraternities |edition=20th |year=1991 |orig-date=1879 |publisher=Baird's Manual Foundation, Inc. |location=Indianapolis, IN |isbn=978-0963715906 |page=V-14–18}}</ref>
Delta Sigma Pi was established to foster the study of business at the university level. Its goals include: 
* to encourage social activity among business students, 
* to build relationships with the commercial world, 
* to promote strong ethical standards, and 
* to enhance the civic and commercial welfare of the community.<ref name="Baird's" />
The second chapter was founded at [[Kellogg School of Management|Northwestern School of Commerce]]. National meetings, called the Grand Chapter Congress, became a regular tradition and to this day the national fraternity meets every other year to conduct business and elect its national leaders.<ref name="bylaws">[http://www.dspnet.org/site/images/pdfs/manuals/Bylaws.pdf Delta Sigma Pi National Bylaws (34th Edition)]</ref>

After rapid expansion in the early 1920s, the fraternity opened its national headquarters in [[Chicago]], [[Illinois]] in 1924.<ref name="history">{{cite web |url=http://www.dspnet.org/site/index.php?option=com_content&view=article&id=26&Itemid=20 |title=History of Delta Sigma Pi |author=James Prescott |work=Delta Sigma Pi Website |publisher=Delta Sigma Pi |access-date=November 15, 2010 |archive-date=January 16, 2015 |archive-url=https://web.archive.org/web/20150116214657/http://www.dspnet.org/site/index.php?option=com_content&view=article&id=26&Itemid=20 |url-status=dead }}</ref> In 1957, the central office moved to [[Oxford, Ohio|Oxford]], [[Ohio]] adjacent to the campus of [[Miami University]].<ref name="history" /><ref name="Baird's" />

The biggest change in the history of the Fraternity took place in 1975, as the Board of Directors mandated that chapters were allowed to initiate female business students, to conform with [[Title IX]].

== Symbols ==
The badge of Delta Sigma Pi is a skull and crossbones, superimposed on a wreath of leaves.  The letters '''{{lang|grc|Δ}}''', '''{{lang|grc|Σ}}''', and '''{{lang|grc|Π}}''' are inscribed on the skull, set with amethyst eyes, a crown on top highlighted in red lacquer, often enhanced with surrounding pearls.<ref name="Baird's" />

The colors of Delta Sigma Pi are old gold and royal purple.<ref name="Baird's" /> The red rose was adopted as the flower of Deltasig at the first Board of Directors meeting in 1921. It was primarily the gift given to the wives and courted women of Deltasig brothers (which at the time was still all male). One of the founding members, Harold V. Jacobs, suggested a rose as the official fraternity flower because his wife loved roses and it was also her first name (Rose Jacobs). Five years later, in 1926, Jacobs also suggested that the song currently sung at LEAD schools and Grand Chapter Congress events, ''Rose of Deltasig'' be adopted as the official song of the fraternity.<ref>Noted by Los Ellis via the official Deltasig website and Central Office archives in Oxford, Ohio.</ref>

In 1911 the fraternity published its first newsletter, which soon would be named ''The Deltasig''.
