The modern German term Geier generally is recognized as referring to two distinct families of carrion-eating bird whose range includes the whole of Europe and the western part of Asia. Geier refers both to birds from the genus Old World vulture (Aegypiinae) and the family New World vulture (Cathartidae).
In English usage, the word Geier has been associated with both the Gyrfalcon and the Lammergeier although neither is synonymous with “Geier”. For example, "gyrfalcon" is thought to come from French gerfaucon, which is written in mediaeval Latin as gyrofalco, but the first part of the word also is said to come from Old High German gîr (now Geier), as in "vulture". *
The modifier, "Gyr", “Gier” or "Geier" preceding the word "falcon" is now thought to be a reference to the large size of the bird rather than to its genus or family *
, but it has not always been so regarded.
Earlier inaccurate and misleading conflations of these disparate terms resulted from reliance on imprecise Biblical translations and metaphorical impressions rather than on direct anatomical or behavioral observations of the bird species themselves. In the King James Version of the Bible, in Leviticus xi, 13; Deuteronomy xiv, 17), the term "Gyrfalcon" referred to an unclean bird, most likely an Egyptian vulture, rather than to the modern Gyrfalcon, and did not refer to a falcon or an eagle. These Biblical references to "Gyrfalcon" (or sometimes "Gierfalcon") probably were a misinterpretation of a Hebrew term more properly translated either as Egyptian vulture or Lammergeier, the latter also known as the "lamb-vulture" or the "bone-breaker vulture", or historically as the "bone crusher" or Ossifrage). See *
and *
This etymological confusion has produced taxonomic confusion, as well. Some authorities actually proclaimed uncertainty whether the Geier is a vulture or an eagle, and older dictionaries used the terms “Geier”, “Gyrfalcon” and “Lammergeier”, almost interchangeably, e.g. Webster's 1913 Dictionary, *
).
Poets and others often assumed that the term Geier refers to a form of eagle or falcon, rather than a vulture, a matter that was commented upon in the article by Harriet C. Stanton, Poets and Birds: a Criticism, The Atlantic monthly. / Volume 52, Issue 311, September 1883. *
Even some encyclopedia writers adopted the view that the Lammergeier "is more closely allied with the eagles than with the vultures", as in the 11th Edition of Encyclopædia Britannica. *
Taxonomic confusion may have resulted from the physical appearance of the Lammergeier. Because the head of the Lammergeier, unlike most other vultures, is feathered rather than naked, it bears a resemblance to the eagle or condor. “Gyrfalcon” is also sometimes rendered as "Geir eagle", as in *
), although in modern usage a Gyrfalcon is a member of the falcon family and is not an eagle. The Indian Vulture, another true vulture species recently recategorized as critically endangered, also was described as having a distinctly "eagle-like bearing" in contrast to most other vulture species. * 
The modern taxonomic distinction between the families of eagles or falcons and the families of vultures should eliminate any uncertainty over the respective meanings of the term Geier. The Egyptian vulture (Neophron percnopterus) and the Lammergeier (Gypaetus barbatus) are true carrion-eating vultures. The term "Geier" should not be applied to the modern Gyrfalcon (Falco rusticolus); the Gyrfalcon is a distinct species of falcon (the largest of the falcon family), and is not a vulture.
Geier is a common surname in Germany and somewhat less common among German-American people. It is also found as a French surname, and as Russian surname. The latter probably is associated with German emigration to Russia in the 17th and 18th centuries. The surname Geier is often considered to be interchangeable with Geyer, although some sources ascribe a different origin and meaning to the two surnames.
Many using the surname Geier share an oral history attributing its origins to a heroic band of peasant villagers who climbed high to an aerie and clubbed to death a gigantic raptor (a "Geier") who had been stealing and eating human babies from their village. See *
Like the surname with its normal German spelling "Geier", the surname "Geyer" is primarily associated with the word "vulture". This is often used in a pejorative sense, however (as in "nickname for a greedy or rapacious person, from Middle High and Middle Low German gir(e) as in ‘large bird of prey’, ‘vulture’"). When affixed to a Jewish family, the surname "Geier" is thought by some to have a slightly different meaning. The Yiddish word "Geyer" means "peddler", and it is assumed that when last names became mandatory in Europe, the surname Geier was imposed upon Jewish peasants as a deprecatory label connoting a scheming merchant who takes advantage of the cupidity of others, i.e., a "vulture". See *
Ironically, the word "Geier" more recently has evolved as a "derogatory term for persons from the Middle East." * 
A significant number of African American people with the surname Geier are found in Washington D.C. and across the Southern States, the European antecedents of which are unknown. As with the surnames of many African American families (See Dunaway, Wilma A., The African American Family in Slavery and Emancipation (Cambridge University Press, 2003), pp. 259-60), it is likely that the names were adopted from a European American slaveowner by the name of "Geier", but none has been identified to date.
The etymological confusion associated with ornithological use of the term "Geier" also has affected family coats of arms and traditions concerning family origins of those bearing the Geier surname. Some oral traditions and family histories associate the Geier surname with the eagle (as in the "Eagle's Nest" coat of arms) and with a peasant legend concerning a baby-stealing bird of prey in a medieval Swabian or Saxon village. *
Others associate the surname with the carrion-eating, bone-crushing variety of vulture. *

In modern times, it is not unusual for the vulture in family coats of arms or logos to be rendered as a comical caricature of a slumping and sad-sack buzzard rather than a lammergeier or gyrfalcon with "the bearing of an eagle." See, e.g., *
An Austrian town known as "Geiersberg im Innkreis" *
follows the preferred spelling of Geier and sometimes is associated with the place of origin of the surname Geier, as well. The castle of Florian Geier, in Giebelstadt, *
has been used to stage dramas commemorating its famous first occupant, but has not otherwise conferred place name recognition on the Swabian region south of Würtburg where it is located.
The ornithological and etymological confusions posed by the name or word "Geier" have led to some interesting and sometimes comical confusions in literary uses of the term, as well.

, the United States Supreme Court held that the federal legislation requiring passive restraints in motor vehicles sold in the United States pre-empted state tort law. The plaintiff was a child named Alexis Geier who had been seriously injured in an accident while riding with her parents in a Honda passenger vehicle equipped with seat belts but not airbags. The Supreme Court held that Ms. Geier could not sue Honda for failing to install airbags in a vehicle sold in 1987 because at that time, only seatbelts were required by federal law.The other case, commonly known as the "Geier Case", involved an African American teacher named Rita Sanders at what was then Tennessee State College, now the Tennessee State University, who sued on behalf of herself and others in a class action to compel the State of Tennessee to end its de facto operation of a dual post-secondary education system for white and non-white students. This litigation was initiated by Ms. Sanders in 1968. Ms. Sanders later married and became known as Rita Sanders Geier. The case had a tortuous history as the United States Government and a number of other plaintiffs joined in support of her position, and involved at least a dozen reported appellate court decisions, including Geier v. Sundquist, 94 F.3d 644 (6th Cir. 1996); Geier v. Richardson, 871 F. 2d 1310 (6th Cir. 1989); Geier v. Alexander, 801 F.2d 799 (6th Cir. 1986); Geier v. Alexander, 593 F. Supp. 1263 (M.D. Tenn. 1984); Geier v. University of Tennessee, 597 F.2d 1056 (6th Cir.), cert. denied, 444 U.S. 886 (1979); Geier v. Blanton, 427 F. Supp. 644 (M.D. Tenn. 1977); Geier v. Dunn, 337 F. Supp. 573 (M.D. Tenn. 1972); and Sanders v. Ellington, 288 F. Supp. 937 (M.D. Tenn. 1968). The case was "resolved" 38 years later by a consent decree or settlement agreement in 2001, which imposed a 5-year period for implementation of various programmatic measures (colloquially known as Geier programs) to unwind 200 years of segregation and discrimination in the system of public higher education in Tennessee. *
The final confirmation of the Consent Decree was approved in September 2006. As stated in the Joint Statement in Support of the Consent Decree, "The Geier case stands first in terms of time and precedent in a line of cases devoted to the removal of a variety of vestiges of segregation from systems of public higher education." *

The origins of the tribal label "Geier" are obscure if not apocryphal. In this context, the word "Geier" may be a mistranscription of the Spanish word Quier (a form of Eng. want), or it may be a mistranscription or transliteration of the Spanish word Guiar (Sp. for "guide" or "lead"), rather than an accurate phonetic rendition of the tribal name from its own language.
Geier is also the name of a bakery chain in Vienna, Austria.
Well known representatives of the Geier surname include the Geier Glove Company (*
) and the Geier Sausage Company (*

Another well-known representative of the Geier name was the founder of the Cincinnati Milling Machine Corporation (originally the Cincinnati Screw and Tap Company), Frederick V. Geier,*
whose company is still controlled by the Geier family (but now known as Cincinnati Milacron, Inc. *
). This branch of the Geier family has been prominent in Cincinnati civic and social affairs since the early 1900s, and has endowed the Geier Collections and Research Center of the Museum of Natural History and Science in Cincinnati. *

The infamous Mark Geier and his misguided son, David Geier, have established an unenviable and unsavory reputation for themselves and besmirched the name Geier by touting an untenable and fallacious concoction of unprincipled, fabricated "research" results designed to undermine the validity of stem cell research. They have been largely discredited as a result. *
