Dr. Robert B. Klotz, son of Jeremiah and Carolina (Seip) Klotz, was born in South Whitehall Township, Lehigh County, October 25, 1872. His early life was spent in Guthsville, and his education was received in the public schools and Muhlenberg College, after which he entered Jefferson Medical College, after which he entered Jefferson Medical College at Philadelphia, in 1890, from which he graduated in 1893. He then located at Marysville, Ohio, where he was connected with the celebrated Doctors, Charles and William Hamilton. He practiced successfully for one year, when owing to ill health, his parents requested him to return to his native state. In the fall of 1894, he located at Rittersville, where he established a large practice, having been the first physician there. He served as physician of the Lehigh County almshouse for eight years. In addition to his practice, Dr. Klotz entered the real estate field, becoming one of the promoters of Dixon Park, at Rittersville, and personally sold those lots, which are now practically all built upon. Later, he purchased a number of other tracts, which he divided into lots which he readily sold. Through purchase he procured the Frank Texler farm, consisting of fifty-two acres, adjoining the Manhattan Hotel. This property he divided into logs, attended in person to the grading of the streets, and gave lots free to people who agreed to build upon them. Upon this farm was situated a old barn, which Dr. Klotz transferred to the firm of Klotz & Bergenzer, silk ribbon manufactures, also six lots were made out in their name. This firm of which Dr. Klotz is the senior member, commenced business with two looms, which number has now been increased to nineteen and they give employment to thirty-two people. After in installation of seven more looms to the original two, the barn became too small for their use, and the firm built upon the south side of the pike, adjoining Central Park. In 1906, Dr. Klotz erected his residence along the pike and the residence of his partner is situated two doors west. White Dr. Klotz was engaged in disposing of the fifty-two acre tract, he purchased different tracts of the Jacob Saeger farm in East Allentown, from time to time. This property he also cut into lots, disposing of them at a later date. The dividing of these tracts into lots was always followed by the building of a number of houses. After the laps of a shod time, Dr. Klotz and Herman Hildebrand of East Allentown, purchased a thirty-two acre tract of land from Jacob Saeger. The land was located in East Allentown and was also cut into building lots. In 1912, sixty houses were erected on this tract and it was entirely through the efforts of Dr. Klotz that the silk mill at East Allentown was erected, which at the present time is the largest narrow ribbon mill in the world and the pay roll of its employees amounted to $17,000 semimonthly. Dr. Klotz also has the Abbott Fuller farm of eighty acres situated in Hanover township. In 1911 the firm of Klotz & Brgeenzer purchased the Lewis Koch farm, of fiftythree acres, situated on Bath Road, through the center of which the Allentown & Bethlehem Boulevard has been opened.

In 1912, Dr. Klotz purchased the William Fenchel farm at Rittersville, containing thirty-four acres, which lies adjacent to a tract of land consisting of forty-one acres, which the firm of Klotz & Bregenzer, purchased in 1914, which two farms have likewise been cut up into building lots. The Allentown and Bethlehem Boulevard passes through the middle of both farms. Early in the spring of 1914, Dr. Klotz sold five acres of the above land to Legh Meyer, of Bethlehem.

On account of failing health, and owing to his vast real estate transactions, Dr. Klotz disposed of his medical practice to Dr. V. J. Gangewere in August, 1907

In Politics, Dr. Klotz is a Democrat. He was a school director and supervisor of Hanover Township During his term of office as a school director and largely through his efforts, the present modern four-room school building was erected at Rittersville, in 1907. He also succeeded in getting the Bethlehem City Water Company extended to Rittersville, and in three days he had secured subscriptions to the amount of $720,000, a sufficient amount of subscriber to warrant the company to make the extension. Late the following year the people of East Allentown requested him to secure water service for them and he succeeded in doing so. The improvements at Rittersville and East Allentown are due, in a large measure to the extension of the Bethlehem water company mains. Dr. Klotz served as chairman of the organization and later as president of the first fire company at Rittersville in all five years. The company was organized largely through the efforts of Dr. Klotz after the fire in 1905 when six houses were destroyed. The company how has a membership of one hundred and twenty-five. They purchased a chemical engine at a cost of $1,500, and erected an engine house. Dr. Klotz was a director of the Bethlehem Trust Company from its organization up to 1910, when he resigned to accept a similar position in the Citizens' Deposit and Trust Company of Allentown. He is a member of St. Peter's Lutheran Church.

Dr. Klotz has been most active in church and Sabbath school work since 1909, at which time he was elected to the office of deacon in the church and superintendent of the Sunday school. He has filled both offices with humbleness and great efficiency ever since. He was a member of the building committee of St. Peter's Lutheran church, Rittersville, which was erected in 1913 and completed in 1914 at a total cost of approximately $35,000. Dr. Klotz and family contributed the large bell and altar in this beautiful edifice.
