Died: 8 October 1883 in Kirksville Benton Township, Adair, Missouri, USA

Enoch Beery Seitz' parents were Daniel Seitz and Catherine Beery. Daniel (born in 1791 in Rockingham County, Virginia) was a farmer. He married Elizabeth Hite in June 1813 and they had eleven children but Elizabeth died in 1831. Following the death of his first wife, he married Catherine Beery (born in 1808 in Fairfield County, Ohio), a second cousin, on 15 April 1832. Enoch Beery Seitz was one of Daniel and Catherine's eight children, being the third of their four sons. He was brought up on the family farm and had little formal education at this stage, only taking the common-school course. However, the boy was always keen to learn and it is said that he would plough the fields reading a book propped up on the plough. Finkel writes [6]:-

Possessing a great thirst for learning, he applied himself diligently to his books in private and became a very fine scholar in the English branches, especially excelling in arithmetic. It was told to the author, by his nephew Mr Huddle, that when Seitz was in the field with a team, he would solve problems while the horses rested. Often he would go to the house and get in the garret where he had a few algebras upon which he would satiate his intellectual appetite. This was very annoying to his father who did not see the future greatness of his son, and many and severe were the floggings he received for going to his favourite retreat to gain a victory over some difficult problem upon which he had been studying while following the plough. Though the way seemed obstructed, he completed algebra at the age of fifteen, without an instructor.

His father Daniel died in October 1864 and, in about 1866, his mother Catherine, together with Enoch and another couple of her children, moved to Greenville, Ohio. Seitz attended a normal school at Greenville and then enrolled at the Wesleyan College in Delaware, Ohio. He did not take mathematics courses at the College but continued to study mathematics in his own time. He left the Wesleyan College in 1870 without graduating and, in 1872, was appointed as an assistant teacher at the Greenville Normal School. On 24 June 1875, Seitz married Anna Elizabeth Kerlin. Anna, whose parents were William Kendrick Kerlin and Hannah Jefferis, was born in Wayne County, Indiana on 27 December 1854. She had moved with her parents to Greenville, Ohio in 1865 where her father was a banker. Anna became a school teacher in 1872 and taught until her marriage to Seitz. Enoch and Anna Seitz had four sons: Ray E Seitz studied law at the University of Cincinnati; Willie Kerlin Seitz became a science teacher in Lancaster, Missouri; Clarence D Seitz died in 1886 at the age of four; and Enoch Beery Seitz excelled in science and mathematics. Seitz's contributions to Greenville were spoken about in an address to the Darke County Teachers' Association following his death [4]:-

... while he was perfectly at home in the sciences, mathematics seemed to be his delight. The more difficult the question, the more determined was he to master it, and from [1872 to 1879], I never knew him to fail in the solution of any problem he undertook. ... For a number of years he filled the position of principal in the Greenville high school with ability and entire satisfaction. As a member of the board of county school examiners, the teachers will remember him as being consistent, kind and obliging; ever willing to encourage the despondent, assist the needy, and by influence and example lead them to a higher sphere of usefulness. As chairman of the executive committee of our Institute, he was honest, conscientious, and, whether in the discharge of financial duty, or in a demonstration before the Institute, he seemed to possess the same earnest determination to do his whole duty faithfully.

In 1879 Seitz was appointed as a teacher at the North Missouri State Normal school in Kirksville, Missouri (now called Truman State University) [4]:-

When he left Greenville for his field of labour in Missouri, nearly a hundred teachers accompanied him to the train, and he was cheered and encouraged by their kind wishes and congratulations.

The family moved to Kirksville, but Seitz died of typhoid fever four years later. He had just accepted the position of professor of mathematics at the University of Texas but died before being able to take up the post [8]:-

Following Enoch's death in 1883, Anna returned to Greenville and resumed her teaching career for nine years. She then returned to Kirksville as a professor at the Normal School and principal or supervisor of its demonstration school from 1894 to 1898. Her three surviving sons began attending the Normal School. During this period, Anna also began attending Columbian School of Osteopathy, from which she graduated in 1899, becoming a doctor of osteopathy. She practiced in Richmond, Indiana, Cape Girardeau, Missouri, and Phoenix, Arizona. In early 1904, Anna completed for a post-graduate course at Kirksville's American School of Osteopathy (at the time a separate institution from Columbian). In February of that year, she returned to Greenville, Ohio, where she became the only female osteopathic practitioner in Darke County. Anna died on 19 February 1918.

We have said nothing yet of Seitz's mathematical contributions. A Memorial Plaque, dedicated to Seitz's memory in 1929, is in the old Bremen High School. It reads:-

To the Memory of Enoch Beery Seitz, One of the World's Greatest Mathematicians.

Benjamin Finkel [5] describes Seitz as:-

... the most distinguished mathematician of his day.

Although these might appear as exaggerated claims, one has to see them in the context of mathematics in the United States in the 1870s. This must be seen as a period when there was little research level mathematics being done anywhere in the country yet there was a lively interest in challenging mathematical problems and puzzles which set the scene for the later rapid move to high powered research. Seitz, although he died at the age of 37, contributed over 500 published problems and solutions in the Analyst, the Mathematical Visitor, the Mathematical Magazine, the School Visitor, and the Educational Times of London. Artemas Martin had founded the Mathematical Visitor and the Mathematical Magazine, and he wrote following Seitz's death:-

A star has fallen ... in the early prime of manhood, and the scientific world is called to mourn the untimely loss of one of the brightest mathematical intellects ever imprisoned in mortal clay.

Seitz was particularly fond of problems involving averages and probabilities. We give six examples of problems he posed or solved:

1. Find the average area of a spherical triangle.
2. A cube is thrown into the air and a random shot fired through it; find the chance that the shot passes through the opposite side.
3.  
4. Find the equation to the locus of the centres of all the circles that can be incribed in a given semi-ellipse.
5. A straight tree growing vertically on the side of a mountain was broken off by the wind, but not severed; find the chance that the top reaches the ground.
6. A boy stepped upon a horizontal turn-table while it was in motion, and walked across it keeping all the time in the same vertical plane. The boy's velocity is supposed to be uniform in his track on the table, and the motion of the table toward him. The velocity of a point In the circumference of the turn-table is ntimes the velocity of the boy along the curve he describes. Required the nature of the curve the boy describes on the table, and the distance he walks while crossing it (1) when n is less than 1, (2) when n equals 1, (3) when n is greater than 1.

Although Seitz died in Kirksville, his body was taken to Greenville, Ohio where he was buried. J P Blanton was head of the North Missouri Normal School in Kirksville where Seitz taught for the final four years of his life. He brought Seitz's body back to Greenville and gave the following tribute to Seitz at the burial [4]:-

Four years ago, on an August day, there was great commotion in your usually quiet village. The man whose dust lies before us today, with his young wife, was bidding farewell, to the home of their childhood, he to resume the responsibilities of an honourable position in a distant western state; she, with Naomi-like spirit, to be his help meet to kindle the fires upon a new hearthstone. Then, as today, crowds assembled, teachers, pupils and friends of all callings came around him to bid him good speed, to shake his hands, to predict for him a brilliant career in his new sphere of labour, and to congratulate him that his great abilities had been recognized in a fitting manner. If tears were shed then, they were tears mingled with glad smiles, they were the tears of those who wept with a hope that that manly form would again be a familiar figure on the streets, and that possibly after years of successful labour at his profession he would spend the evening of life here among his earliest friends. Alas! alas! all that Missouri can send back of Ohio's gifted son is his poor dust to rest in her bosom until the resurrection morn.

Did I say all? Nay, it is not all. She sends back to you the record of his life, as pure and unsullied as an angel's wing. She bids me say to you that his work and life have left a lasting impression upon thousands of her noblest youth, that his memory is enshrined in the hearts of her people and that the tears of devoted students, fellow teachers and citizens of all classes have stained his coffin lid. From the beginning of his sickness, which was of unusual severity from the very first, every possible attention has been shown him, physicians gave up their practice and spent their days and nights by his bedside; medical skill exhausted every resource.

The students, all of whom loved him like a brother, vied with each other in their ministrations. They were the first to be with him and some of them were bending over him when the last feeble breath left his body. Even the little children on the streets would stop me and say, "How is Professor Seitz today?" And when I would sometimes cheer them with hopes that I hardly dared to entertain, their brightening faces were eloquent of love and esteem in which he was held by his fellow townsmen.

Enoch Beery Seitz was an extraordinary man. He commanded, without effort, the respect of everybody. He was a man of the most singularly blameless life I ever knew. His disposition was amiable, his manner quiet and unobtrusive, and his decision, when circumstances demanded it, was prompt and firm and immovable as rocks. He did nothing from impulse; he carefully considered his course, and with almost infallible judgment came to conclusions that his conscience approved, and then nothing could move him. While he never made an open profession of religion, he was a profoundly religious man. He rested his hopes of salvation in the sacrifice of the tender and loving Saviour, and I am thoroughly convinced he has entered into that rest which remains for the people of God. What a comfort this must be to the tender, brave, faithful young wife he has left behind him, to his bereaved old mother, and to all his mourning friends assembled around his ashes today. No need, dear partner of my dear friend, no need, bereaved mother, no need, dear mourning friends, for you to ask human sympathy or skill to pluck from your memories a rooted sorrow, to raise out the withering troubles of the brain with some sweet oblivious antidote cleanse the stifled bosom of that perilous grief that now weighs so heavily on your hearts. No need, I say, to sorrow. ...
