Jacob Steiner (Steiner Erik, Budapest) is a professor at Hebrew University of Jerusalem, and a researcher of the physiology of the senses.
He received his Ph.D. from University of Basel in 1964.
He became a lecturer in 1965, a senior lecturer in 1974, an associate professor in 1979 and became emeritus in 1996.
He was a visiting associate professor to the University of Pennsylvania. He was a visiting professor to Brown University. He was a visiting scholar at Monell Chemical Senses Center, in Philadelphia.
He did research on the physiology of the senses of taste and smell in man and in animals and their clinical trial. On the behavioral, electrophysiological and autonomous reactions to chemical stimuli. And on the developmental aspects of oral functions.
"Steiner’s research, which involved infants only a few hours old, clearly shows that humans are born with the capacity to distinguish between various tastes. Jacob E. Steiner, a taste researcher at Hebrew University in Jerusalem, almost all babies, when tasting sweet stimuli, show a ’’marked relaxation of the face, resembling an expression of ’satisfaction.’ ’’ This expression is often followed by a slight smile and even ’’eager licking of the upper lip.’’ When the babies were fed a bitter solution, on the other hand, their facial expressions turned to ’’dislike and disgust or rejection.’’" New York Times April 16.1989. Can Society Tell You What Tastes Good?
"The meticulous observation, semiquantitative analysis and evaluation of behavioral reactions is proposed as one of the most relevant and valid avenues of investigation on the workup of chemosensory stimuli by the living organism. Behavioral manifestations, are probably even in a much easier way "readable" indicators of pleasure and displeasure than any other event-related bodily manifestation. In fact, the phenomenon of bacterial chemotaxis (as usually divided in positive- respectively negative chemotaxis) belong to the same category or kind of innate, probably even inherited reflectory mechanisms expressing " acceptance" - 'indifference' and 'aversion' of the organism." Jacob E. Steiner
Lars Ernster, Edith Ernster and Jacob Steiner lived during World War II in the office of the Swedish Embassy in Budapest Üllöi ut 2–4. Initially, there were 250 workers; later about 400 people working around the clock (Edith Ernster remembers Raoul Wallenberg). During the night of 8 January 1945, all inhabitants were dragged away by an Arrow Cross Party executing brigade of the city commandership near to the Danube banks. At midnight, twenty policemen with drawn bayonets broke into the Arrow Cross house and rescued everyone. [1] Among the saved persons, Lars Ernster returned to Sweden and Jacob Steiner went to Israel. Lars Ernster was a member of the Board of the Nobel Foundation from 1977 to 1988. Jacob Steiner is a professor at the Hebrew University of Jerusalem.
Information from Jacob Steiner after he has read this page: On December 25, 1944, Jacob Steiner's father was shot dead by Arrow Cross militiamen, falling into the Danube as a result. His father had been an officer in World War I and spent four years as a prisoner of war in Russia. [2]

Fear is an intensely unpleasant primal emotion in response to perceiving or recognizing a danger or threat. Fear causes psychological changes that may produce behavioral reactions such as mounting an aggressive response or fleeing the threat. Fear in human beings may occur in response to a certain stimulus occurring in the present, or in anticipation or expectation of a future threat perceived as a risk to oneself. The fear response arises from the perception of danger leading to confrontation with or escape from/avoiding the threat, which in extreme cases of fear can be a freeze response. The fear response is also implicated in a number of mental disorders, particularly anxiety disorders.
A pheromone is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology.
Aversion therapy is a form of psychological treatment in which the patient is exposed to a stimulus while simultaneously being subjected to some form of discomfort. This conditioning is intended to cause the patient to associate the stimulus with unpleasant sensations with the intention of quelling the targeted behavior.
Androstenone (5α-androst-16-en-3-one) is a 16-androstene class steroidal pheromone. It is found in boar's saliva, celery cytoplasm, and truffle fungus. Androstenone was the first mammalian pheromone to be identified. It is found in high concentrations in the saliva of male pigs, and, when inhaled by a female pig that is in heat, results in the female assuming the mating stance. Androstenone is the active ingredient in 'Boarmate', a commercial product made by DuPont sold to pig farmers to test sows for timing of artificial insemination.
Conditioned taste aversion occurs when an animal acquires an aversion to the taste of a food that was paired with aversive stimuli. The effect explains that the aversion develops more strongly for stimuli that cause nausea than other stimuli. This is considered an adaptive trait or survival mechanism that enables the organism to avoid poisonous substances before they cause harm. The aversion reduces consuming the same substance in the future, thus avoiding poisoning.
Aromachology is the study of the influence of odors on human behavior and to examine the relationship between feelings and emotions. Those who practice aromachology are aromachologists. Aromachologists analyze emotions such as relaxation, exhilaration, sensuality, happiness and well-being brought about by odors stimulating the olfactory pathways in the brain and, in particular, the limbic system. Different wearers are thought to have unique physiological and psychological responses to scents, especially those not manufactured synthetically but based on real scents. The word "aromachology" is derived from "aroma" and "physio-psychology", the latter being the study of aroma. This term was coined in 1989 by what is now the Sense of Smell Institute (SSI), a division of The Fragrance Foundation. The SSI defines aromachology as "a concept based on systematic, scientific data collected under controlled conditions". The term is defined as the scientifically observable influence of smell on emotions and moods. Consumers use aromachology to alleviate time pressures, for relaxation or stimulation and as a component of other activities that generate a feeling of well-being.
The Monell Chemical Senses Center is an independent, non-profit scientific research institute located at the University City Science Center campus in Philadelphia. Founded in 1968, it is dedicated to interdisciplinary basic research on the senses of taste and smell. The center's mission is to improve health and well-being by advancing the scientific understanding of taste, smell, and related senses. Monell's research focuses on various aspects of chemosensory science, including how chemical senses affect human health, behavior, and the environment. The center employs a collaborative and interdisciplinary approach, with scientists from diverse fields such as sensory psychology, biophysics, chemistry, behavioral neuroscience, environmental science, and genetics working together on research projects.
The Shoes on the Danube Bank is a memorial erected on 16 April 2005, in Budapest, Hungary. Conceived by film director Can Togay, he created it on the east bank of the Danube River with sculptor Gyula Pauer to honour the Jews who were massacred by fascist Hungarian militia belonging to the Arrow Cross Party in Budapest during the Second World War. They were ordered to take off their shoes, and were shot at the edge of the water so that their bodies fell into the river and were carried away. The memorial represents their shoes left behind on the bank.
Lars Ernster was a professor of biochemistry, and a member of the Board of the Nobel Foundation.
Károly Szabó was an employee of the Swedish Embassy in Budapest from 1944 to 1945 when he rescued Hungarian Jews during the Holocaust. He was a supporter of Raoul Wallenberg and had a significant role in making contact with the representatives of the Hungarian police and other state officials. He was arrested without legal proceedings in 1953 in Budapest, in a secret trial.
Chemesthesis is the detection of potentially harmful chemicals by the skin and mucous membranes. Chemesthetic sensations arise when chemical compounds activate receptors associated with other senses that mediate pain, touch, and thermal perception. These chemical-induced reactions do not fit into the traditional sense categories of taste and smell.
Rachel Sarah Herz is a Canadian and American psychologist and cognitive neuroscientist, recognized for her research on the psychology of smell.
An odor or odour is caused by one or more volatilized chemical compounds that are generally found in low concentrations that humans and many animals can perceive via their sense of smell. An odor is also called a "smell" or a "scent", which can refer to either an unpleasant or a pleasant odor.
The sense of smell, or olfaction, is the special sense through which smells are perceived. The sense of smell has many functions, including detecting desirable foods, hazards, and pheromones, and plays a role in taste.
Olfactory memory refers to the recollection of odors. Studies have found various characteristics of common memories of odor memory including persistence and high resistance to interference. Explicit memory is typically the form focused on in the studies of olfactory memory, though implicit forms of memory certainly supply distinct contributions to the understanding of odors and memories of them. Research has demonstrated that the changes to the olfactory bulb and main olfactory system following birth are extremely important and influential for maternal behavior. Mammalian olfactory cues play an important role in the coordination of the mother infant bond, and the following normal development of the offspring. Maternal breast odors are individually distinctive, and provide a basis for recognition of the mother by her offspring.
A sense is a biological system used by an organism for sensation, the process of gathering information about the surroundings through the detection of stimuli. Although, in some cultures, five human senses were traditionally identified as such, many more are now recognized. Senses used by non-human organisms are even greater in variety and number. During sensation, sense organs collect various stimuli for transduction, meaning transformation into a form that can be understood by the brain. Sensation and perception are fundamental to nearly every aspect of an organism's cognition, behavior and thought.
Gordon Murray Shepherd was an American neuroscientist who carried out basic experimental and computational research on how neurons are organized into microcircuits to carry out the functional operations of the nervous system. Using the olfactory system as a model that spans multiple levels of space, time and disciplines, his studies ranged from molecular to behavioral, recognized by an annual lecture at Yale University on "integrative neuroscience". At the time of his death, he was professor of neuroscience emeritus at the Yale School of Medicine. He graduated from Iowa State University with a BA, Harvard Medical School with an MD, and the University of Oxford with a DPhill.
The Association for Chemoreception Sciences is an international professional society in the field of chemosensory science. It is a non-profit organization that seeks to promote and advance the interests of the science of senses such as taste and smell. In order to do this, it holds an annual meeting that is a scientific forum for the research community and also provides outreach to the public about olfaction (smell), gustation (taste) and chemesthesis.
No study has led to the isolation of true human sex pheromones, although various researchers have investigated the possibility of their existence.
Olfactic communication is a channel of nonverbal communication referring to the various ways people and animals communicate and engage in social interaction through their sense of smell. Our human olfactory sense is one of the most phylogenetically primitive and emotionally intimate of the five senses; the sensation of smell is thought to be the most matured and developed human sense.
