Life and achievements
Early life
Mendel was born on July 20, 1822, in Heinzendorf, part of the Austrian Empire, to a family of German ethnicity. His parents, Anton and Rosine Mendel were farmers, and young Mendel helped his parents with farming and developed an interest in plant breeding. Mendel was a bright child and, because of his talents, was able to attend the gymnasium in Troppau, although his family had little money.
Mendel entered the Philosophical Institute of the University of Olomouc in 1840, where he studied practical and theoretical philosophy and physics. He had to leave school due to poor health and family financial problems, but he continued his studies with the help of his family, especially his sister Theresia, who gave him her dowry. To support his education costs, Mendel entered the Augustinian Abbey of St. Thomas in Brno and took the name Gregor, becoming a monk.
Mendel was able to satisfy his curiosity for knowledge at the abbey. He was inspired by his teachers, especially Johann Karl Nestler, who was researching the heredity of characteristics. Mendel's interest in heredity was also influenced by his physics teacher, Friedrich Franz, and his experience as a substitute high school teacher. Mendel entered university in 1851 to study at the University of Vienna, where he attended lectures from Christian Doppler, a physicist—this formal education period provided him with the tools he needed for his great discoveries.
When Mendel returned to the abbey in 1853, he started teaching and conducting research. His work with the pea plants in the monastery's garden, which he began in 1856, would change how heredity was viewed. Mendel's systematic and organized procedure and data analysis led to the postulation of Inheritance. However, Inheritance also had its share of failures; for example, he failed the oral examination for teacher certification.
Legacy
Mendel is considered one of the most influential scientists in history, as his discoveries became the basis of genetics. Even though Mendel's work was not appreciated initially, he conducted a controlled study on pea plants. He proved how characteristics are passed on through distinct particles called genes. His findings on the laws of segregation and independent assortment became the cornerstones of genetics and revolutionized the knowledge of Inheritance.
Hugo de Vries, Carl Correns, and Erich von Tschermak's reawakening of Mendel's studies in 1900 is considered one of the most significant events in the history of biology. Mendel's principles were soon confirmed and elaborated on, paving the way for the contemporary study of genetics. His ideas of dominant and recessive characteristics and his approach to the statistical analysis of heredity have impacted future scientific research and application in agriculture, medicine, and evolutionary biology.
Mendel's work is not limited to genetics only. His scientific approach was very methodical and precise, and he introduced concepts such as controlled observation, record-keeping, and statistical analysis to scientific research. Mendel also stressed the importance of controlled experiments in discovering the laws of nature. Many institutions and awards are named after him, including the Mendel Medal and the Museum in Brno.
Nevertheless, Mendel's life was not without some troubles. His duties as an abbot of St. Thomas's Abbey restricted his conducting scientific activities; hence, he needed more time for scientific tasks. However, Mendel continued with his experiment until his death in 1884. The disinterment of his body in 2021 and subsequent genomic study provided details of his physical characteristics and tendencies, thus ensuring his place in the science history books.
Thus, Mendel's work remains relevant to this day and is still used by scientists from around the globe. He made significant contributions to genetics, and his works are still used to this date as a basis of biological knowledge. Thus, Mendel's story is a clear example of how the human spirit, curiosity, hard work, and the pursuit of knowledge can transform the world, proving that even a simple monk's work in the garden of a monastery can revolutionize the course of science.
Milestone moments
Mar 17, 1865
Presentation of Mendel's Research
In February and March 1865, Gregor Mendel shared his findings from his experiments on plant hybridization with the Natural History Society of Brno. He recorded his observations and conclusions on cross-breeding pea plants and described the principles of heredity that became the foundation of Mendel's genetics.
Mendel's presentations focused on the laws of segregation and independent assortment that he had identified. He proved that characteristics are inherited from one generation to the other in a definite proportion, thus disproving the blending inheritance theories. Nevertheless, Mendel's work was relatively straightforward and essential; however, it needed to be acknowledged by the scientific community of that period.
Approximately forty scientists attended the sessions; however, the significance of Mendel's findings needed to be better comprehended. His paper, "Experiments on Plant Hybridization," was published in 1866 but did not gain much recognition. Mendel applied statistical methods to biology, and his work was relatively progressive for his time, but the scientific society could not accept such new approaches.
Mendel did not give up recording and explaining his findings, which provided the foundation for the acceptance of his work. His very systematic approach to research and the detailed analysis that he made in his work paved the way for new standards in scientific observation and analysis. Although he did not receive recognition during his lifetime, he was recognized after his death. The presentation of his research in 1865 can be considered the starting point of the new era in the field of heredity.
Oct 24, 1866
Release of the paper "Experiments on Plant Hybridization."
His work, "Experiments on Plant Hybridization," was published in 1866 in the Natural History Society of Brno proceedings. This paper described his findings on the cross-breeding of pea plants and the patterns of Inheritance across generations.
Mendel's paper described the basic concepts of heredity, later called Mendel's Laws. He explained how characteristics are passed on from one generation to the next in terms of discrete factors, which he called alleles, where one factor can overpower another. This work also presented the Law of Segregation and the Law of Independent Assortment, essential principles used in genetics today.
Unfortunately, Mendel's research was not very well known during his time, and the results of his work needed to be recognized. The scientific community at the time was not ready to accept the particulate heredity concept; thus, the paper was primarily disregarded. Exceptionally few people referred to his work in the subsequent decades, and it was in the early 20th century that his work was acknowledged.
The publication of "Experiments on Plant Hybridization" was a turning point in the history of science. Mendel's careful work and precise description of his results gave a reasonable basis for further investigation of genetics. He later changed how people perceived biological Inheritance and contributed to the development of various sciences, medicine, agriculture, and evolutionary biology.
Nov 5, 1900
Rediscovery of Mendel's Work
In 1900, three scientists—Hugo de Vries, Carl Correns, and Erich von Tschermak—independently rediscovered Gregor Mendel's research. While experimenting with plant hybridization, all of them noted that their outcomes correlated with Mendel's principles of heredity.
The reappearance of Mendel's work can be considered one of the most critical events in the history of genetics. De Vries, Correns, and Tschermak recognized Mendel's work as the first to describe the fundamental laws of heredity. This validation of his findings brought Mendel's work to the limelight as the starting point of modern genetics.
This rediscovery was critical in further developing the study of genetics. Mendel's principles of segregation and independent assortment gave an account of how traits are passed down. Other scientists of his time recognized this, resulting in a revival of interest in his experiments and the evolution of genetics as a branch of science.
Thus, the year 1900 can be considered a turning point in the history of science. Mendel's discoveries, which were once ignored, were later appreciated for their significance in explaining the concept of heredity. This led to more research and discoveries in genetics, and thus, Mendel was remembered as the father of modern genetics.

Appointment as the Abbot of St. Thomas's Abbey
Mendel was appointed abbot of St. Thomas's Abbey in Brno in 1868. This position involved many administrative duties that he could not avoid, which greatly affected his research work.
As an abbot, Mendel had to perform numerous administrative and clerical functions, such as managing the abbey's resources and handling conflicts. A significant problem during his rule was the confrontation with the secular authorities concerning special taxes for the church. These responsibilities restricted the time and effort he could give his scientific work.
Mendel paid attention to his scientific interests even though he had a new and responsible position. However, the bureaucratic procedures greatly limited his opportunities for experimenting and sharing his results. This status change in his life was significant because he had to combine his love for science with the responsibilities of being an abbot.
Mendel's position as an abbot shows the difficulties he had to experience to satisfy his scientific curiosity. It also points to his commitment to the monastic community and his organizational skills in handling different tasks. Although the period of his abbotship restricted his scientific production, it did not reduce his contribution to genetics.
