Eugenics

Sir Francis Galton, FRS (16 February 1822 – 17 January 1911) was an English Victorian era statistician, progressive, polymath, sociologist, psychologist, anthropologist, eugenicist, tropical explorer, geographer, inventor, meteorologist, proto-geneticist, and psychometrician. He was a pioneer in eugenics, coining the term itself and the phrase "nature versus nurture".
The exact definition of eugenics has been a matter of debate since the term was coined by Francis Galton in 1883.

Regression toward the mean

He also created the statistical concept of correlation and widely promoted regression toward the mean.
The British polymath Sir Francis Galton first observed the phenomenon in the context of simple linear regression of data points.

Nature versus nurture

He was a pioneer in eugenics, coining the term itself and the phrase "nature versus nurture".
The phrase in its modern sense was popularized by the English Victorian polymath Francis Galton, the modern founder of eugenics and behavioral genetics, discussing the influence of heredity and environment on social advancement.

Psychometrics

Sir Francis Galton, FRS (16 February 1822 – 17 January 1911) was an English Victorian era statistician, progressive, polymath, sociologist, psychologist, anthropologist, eugenicist, tropical explorer, geographer, inventor, meteorologist, proto-geneticist, and psychometrician. As an investigator of the human mind, he founded psychometrics (the science of measuring mental faculties) and differential psychology and the lexical hypothesis of personality.
Psychological testing has come from two streams of thought: the first, from Darwin, Galton, and Cattell on the measurement of individual differences, and the second, from Herbart, Weber, Fechner, and Wundt and their psychophysical measurements of a similar construct.

Efficacy of prayer

He also conducted research on the power of prayer, concluding it had none by its null effects on the longevity of those prayed for.
The efficacy of prayer has been the topic of various scientific studies since Francis Galton first addressed it in 1872.

Correlation and dependence

Karl Pearson developed the coefficient from a similar but slightly different idea by Francis Galton.

Genius

His book Hereditary Genius (1869) was the first social scientific attempt to study genius and greatness.
The assessment of intelligence was initiated by Francis Galton (1822–1911) and James McKeen Cattell.

Lexical hypothesis

As an investigator of the human mind, he founded psychometrics (the science of measuring mental faculties) and differential psychology and the lexical hypothesis of personality.
Sir Francis Galton was one of the first scientists to apply the lexical hypothesis to the study of personality, stating:

His book Hereditary Genius (1869) was the first social scientific attempt to study genius and greatness.
Since the publication of Francis Galton's Hereditary Genius in 1869, and especially with the accelerated development of intelligence tests in the early 1900s, there has been a vast amount of social scientific research published relative to the question of greatness.

Forensic science

He devised a method for classifying fingerprints that proved useful in forensic science.
Faulds wrote to Charles Darwin with a description of his method, but, too old and ill to work on it, Darwin gave the information to his cousin, Francis Galton, who was interested in anthropology.

Weather map

As the initiator of scientific meteorology, he devised the first weather map, proposed a theory of anticyclones, and was the first to establish a complete record of short-term climatic phenomena on a European scale.
In England, the scientist Francis Galton heard of this work, as well as the pioneering weather forecasts of Robert Fitzroy.

Samuel Tertius Galton

His father was Samuel Tertius Galton, son of Samuel "John" Galton.
He was the son of Samuel "John" Galton, a prominent member of the scientific Lunar Society, and the father of Francis Galton the eminent Victorian scientist.

He also invented the Galton Whistle for testing differential hearing ability.
It was invented in 1876 by Francis Galton and is mentioned in his book Inquiries into Human Faculty and its Development, in which he describes experiments to test the range of frequencies that could be heard by various animals, such as a house cat.

Statistics

Sir Francis Galton, FRS (16 February 1822 – 17 January 1911) was an English Victorian era statistician, progressive, polymath, sociologist, psychologist, anthropologist, eugenicist, tropical explorer, geographer, inventor, meteorologist, proto-geneticist, and psychometrician.
The first wave, at the turn of the century, was led by the work of Francis Galton and Karl Pearson, who transformed statistics into a rigorous mathematical discipline used for analysis, not just in science, but in industry and politics as well.

Anticyclone

As the initiator of scientific meteorology, he devised the first weather map, proposed a theory of anticyclones, and was the first to establish a complete record of short-term climatic phenomena on a European scale. Galton was a polymath who made important contributions in many fields of science, including meteorology (the anti-cyclone and the first popular weather maps), statistics (regression and correlation), psychology (synaesthesia), biology (the nature and mechanism of heredity), and criminology (fingerprints).
Sir Francis Galton first discovered anticyclones in the 1860s.

Synesthesia

Number forms were first documented and named in 1881 by Francis Galton in "The Visions of Sane Persons".

Catell, who also studied with eugenicist Francis Galton, went on to found the Psychological Corporation.

Bean machine

quincunx
Galton's development of the law of regression to the mean, or reversion, was due to insights from the quincunx and his studies of sweet peas.
The bean machine, also known as the Galton Board or quincunx, is a device invented by Sir Francis Galton to demonstrate the central limit theorem, in particular that the normal distribution is approximate to the binomial distribution.

Biostatistics

He went on to found the biometric approach to the study of heredity, distinguished by its use of statistical techniques to study continuous traits and population-scale aspects of heredity.
Francis Galton tried to expand Mendel's discoveries with human data and proposed a different model with fractions of the heredity coming from each ancestral composing an infinite series.

Karl Pearson

This approach was later taken up enthusiastically by Karl Pearson and W.F.R. Weldon; together, they founded the highly influential journal Biometrika in 1901.
Pearson was a protégé and biographer of Sir Francis Galton.

Later in life, Galton proposed a connection between genius and insanity based on his own experience: Men who leave their mark on the world are very often those who, being gifted and full of nervous power, are at the same time haunted and driven by a dominant idea, and are therefore within a measurable distance of insanity Galton attended King Edward's School, Birmingham, but chafed at the narrow classical curriculum and left at 16. His parents pressed him to enter the medical profession, and he studied for two years at Birmingham General Hospital and King's College London Medical School.

Historiometry

To test this, he invented the methods of historiometry.
Historiometry started in the early 19th century with studies on the relationship between age and achievement by Belgian mathematician Adolphe Quetelet in the careers of prominent French and English playwrights but it was Sir Francis Galton, a pioneering English eugenist who popularized historiometry in his 1869 work, Hereditary Genius.
