Question: Who swam with geese as part of his studies of animal behavior?
About the article "Human swimming", section "Occupation".

Candidate passages:
Some occupations require the workers to swim.
For example, abalone- or pearl-divers swim and dive to obtain an economic benefit, as do spear fishermen.
Swimming is used to rescue people in the water who may be in distress, including tired swimmers, non-swimmers who have accidentally entered the water, or water users who have come to harm.
Lifeguards or volunteer lifesavers are deployed at many pools and beaches worldwide to fulfill this purpose, and they, as well as rescue swimmers, may use specific swimming styles for rescue purposes.
Swimming is also used in marine biology to observe plants and animals in their natural habitat.
Other sciences use swimming, for example Konrad Lorenz swam with geese as part of his studies of animal behavior.
Swimming also has military purposes.
Military swimming is usually done by special forces, such as Navy SEALs.
Swimming is used to approach a location, gather intelligence, sabotage or combat, and to depart a location.
This may also include airborne insertion into water or exiting a submarine while it is submerged.
Due to regular exposure to large bodies of water, all recruits in the United States Navy, Marine Corps, and Coast Guard are required to complete basic swimming or water survival training.
Swimming is also a professional sport.
Companies sponsor swimmers who are at the international level.
Many swimmers compete competitively in order to represent their home country in the olympics.
Cash awards are also given at many of the major competitions for breaking records.
Professional swimmers may also earn a living as entertainers, performing in water ballets.
In psychology, imprinting is any type of rapid learning that occurs in a particular life stage that is occurs independently of the outcome of behavior.
Konrad Lorenz is well known for his classic studies of filial imprinting in graylag geese.
Lorenz studied a phenomenon in which the geese bonded with the first moving object they encounter.
This seemed to be irreversible and only developed during a brief “critical period,” which was about 24 hrs after hatching. 
Oskar Heinroth (1 March 1871 – 31 May 1945) was a German biologist who was one of the first to apply the methods of comparative morphology to animal behaviour, and was thus one of the founders of ethology.
His extensive studies of behaviour in the Anatidae (ducks and geese) showed that instinctive behaviour patterns correlated with taxonomic relationships determined on the basis of morphological features.
He also rediscovered the phenomenon of imprinting, reported in the 19th century by Douglas Spalding but not followed up at the time.
His results were popularised by Konrad Lorenz, whose mentor he was.
Lorenz regarded Heinroth as the true founder of the study of animal behaviour seen as a branch of zoology.
Heinroth was born in Mainz-Kastel.
He began his studies of duck and goose behaviour while working as a scientific assistant from 1898 to 1913.
He subsequently became the director of the Berlin Aquarium, a post he held for more than 30 years.
He died in Berlin. 
The field of neuroethology owes part of its existence to the establishment of ethology as a unique discipline within the discipline of Zoology.
Although animal behavior had been studied since the time of Aristotle (384-342 BC), it was not until the early twentieth century that ethology finally became distinguished from natural science (a strictly descriptive field) and ecology.
The main catalysts behind this new distinction were the research and writings of Konrad Lorenz and Niko Tinbergen.
Konrad Lorenz was born in Austria in 1903, and is widely known for his contribution of the theory of fixed action patterns (FAPs): endogenous, instinctive behaviors involving a complex sequence of movements that are triggered (“released”) by a certain kind of stimulus.
This sequence always proceeds to completion, even if the original stimulus is removed.
It is also species-specific and performed by nearly all members.
Lorenz constructed his famous “hydraulic model” to help illustrate this concept, as well as the concept of action specific energy, or drives.
Niko Tinbergen was born in the Netherlands in 1907 and worked closely with Lorenz in the development of the FAP theory; their studies focused on the egg retrieval response of nesting geese.
Tinbergen performed extensive research on the releasing mechanisms of particular FAPs, and used the bill-pecking behavior of baby herring gulls as his model system.
This led to the concept of the supernormal stimulus.
Tinbergen is also well known for his four questions that he believed ethologists should be asking about any given animal behavior; among these is that of the mechanism of the behavior, on a physiological, neural and molecular level, and this question can be thought of in many regards as the keystone question in neuroethology.
Tinbergen also emphasized the need for ethologists and neurophysiologists to work together in their studies, a unity that has become a reality in the field of neuroethology.
Unlike behaviorism, which studied animals' reactions to non-natural stimuli in artificial, laboratory conditions, ethology sought to categorize and analyze the natural behaviors of animals in a field setting.
Similarly, neuroethology asks questions about the neural bases of "naturally occurring" behaviors, and seeks to mimic the natural context as much as possible in the laboratory.
Although the development of ethology as a distinct discipline was crucial to the advent of neuroethology, equally important was the development of a more comprehensive understanding of Neuroscience.
Contributors to this new understanding were the Spanish Neuroanatomist, Ramon y Cajal (born in 1852), and physiologists Charles Sherrington, Edgar Adrian, Alan Hodgkin, and Andrew Huxley.
Charles Sherrington, who was born in Great Britain in 1857, is famous for his work on the nerve synapse as the site of transmission of nerve impulses, and for his work on reflexes in the spinal cord.
His research also led him to hypothesize that every muscular activation is coupled to an inhibition of the opposing muscle.
He was awarded a Nobel Prize for his work in 1932 along with Lord Edgar Adrian who made the first physiological recordings of neural activity from single nerve fibers.
Alan Hodgkin and Andrew Huxley (born 1914 and 1917, respectively, in Great Britain), are known for their collaborative effort to understand the production of action potentials in giant squid neurons.
The pair also proposed the existence of ion channels to facilitate action potential initiation, and were awarded the Nobel Prize in 1963 for their efforts.
As a result of this pioneering research, many scientists then sought to connect the physiological aspects of the nervous and sensory systems to specific behaviors.
These scientists – Karl von Frisch, Erich von Holst, and Theodore Bullock – are frequently referred to as the “fathers” of neuroethology.
Neuroethology did not really come into its own, though, until the 1970s and 1980s, when new, sophisticated experimental methods allowed researchers such as Masakazu Konishi, Walter Heiligenberg, Jörg-Peter Ewert, and others to study the neural circuits underlying verifiable behavior. 
In video games.
Geese first appears in the original ', where he hosts the "King of Fighters" tournament.
The central plot of the game centers around the Bogard brothers' (Terry and Andy) quest to avenge their father's death, who was murdered by Geese a decade before the events of the game.
After the player defeats Geese (who is the final boss), Geese falls off from the building, being declared dead during the game's ending.
Geese does appear in the revised version of "Fatal Fury 2", "Fatal Fury Special", where it is revealed that he survived his fall at the end of the first game. '
centers around Geese's attempt to return to power by collecting the "Sacred Scrolls of Jin", which is said to give their holder great power.
In the next game, "Real Bout Fatal Fury", Geese is once again the final boss in the single-player tournament, confronting the player atop Geese Tower.
In either, Terry's or Andy's ending, Geese falls off his tower once again, refusing to accept help from either of the Bogard brothers.
Geese appears in the subsequent game which does not feature a plot, "Real Bout Fatal Fury Special", as a hidden final boss named Nightmare Geese.
He also appears as a regular character in "Real Bout Fatal Fury 2", which neither contain storyline.
Geese also makes an appearance in the second game in the "Art of Fighting" series.
"Art of Fighting 2", which is set a decade before the first "Fatal Fury", features a younger Geese Howard as the corrupt police commissioner of Southtown.
Geese is revealed to be Mr. Big's boss and the mastermind behind the events of the previous game such as the kidnapping of Yuri Sakazaki.
If the player wins every match against all the previous computer-controlled opponents without losing a round, the player's character will face Geese Howard as a hidden final boss.
In the crossover video games "NeoGeo Battle Coliseum" and the "SNK vs. Capcom" series, Geese appears as a playable character; in the latter he commonly appears as a boss character.
Geese also appears in a few games in "The King of Fighters" series, which does not follow the continuity established by the "Fatal Fury" and "Art of Fighting" games, despite sharing many characters and plot elements.
In "The King of Fighters '96", Geese serves as the leader of the "Boss Team" along with former subordinate Mr. Big and rival Wolfgang Krauser, seeking to find the Orochi power.
Geese would appear again in an non-playable role as the sponsor of the "Special Team" in "The King of Fighters '97", which is composed of Billy Kane, Blue Mary, and Ryuji Yamazaki.
The team would reappear in "The King of Fighters 2003" renamed "Outlaw Team", with Mary (now part of the Women Fighters Team) replaced by Gato from "Mark of the Wolves".
Geese also appears in "The King of Fighters 2000" as a striker, in the Xbox version of "The King of Fighters 2002" and "The King of Fighters XI" as a selectable character, as well as in "The King of Fighters '98: Ultimate Match", which brings back the Boss Team from 96".
He is also a playable character in "The King of Fighters 2002 Unlimited Match", alongside his "Nightmare" variant.
The younger version of Geese from "Art of Fighting 2" also appears as a boss in "The King of Fighters Neowave".
In "The King of Fighters EX: Neo Blood" Geese organizes a new tournament in order to obtain the power from the participant Iori Yagami.
After Iori is defeated, Geese will act as a boss character.
In ' and "Regulation A", Geese is playable under the name of Nightmare Geese.
