Richard Henry Jahns (Dick Jahns)(March 10, 1915 - December 31, 1983) was a mineralogist, petrologist, and geologist. He was born on March 10, 1915, in Los Angeles, California but grew up in Seattle in Washington, and died on New Year's even on December 31, 1983, with the reason of a massive heart attack while he was 68 age at that time.

Dick Jahns graduated from Seattle High School as a class valedictorian and continued his studying in the California Institute of Technology when he was 16 years old. During the life of the college, he demonstrated a keen interest in the areas of petrology, sports, train lines, and geology. In 1935, Dick entered Northwestern University for his interest of geology after the graduation from the California Institute of Technology where he returned to work on his PhD in geology in 4 years, and completed his Phd in 1943.

Dick Jahns has employed in four organisations in sequence, United States Geological Survey, California Institute of Technology, Pennsylvania State University, and Stanford University. His exploration and teaching contributed a huge of achievements on the areas of Geology and Earth Environment.

He lived with Frances, Alfred, Jeannette, and Clayton who are his wife, his son, his daughter and his grandchild respectively before he died. .

Richard Henry Jahns (Dick Jahns) was a mineralogist, petrologist, and geologist. He was born on March 10, 1915, in Los Angeles, California but grew up in Seattle in Washington, and died on New Year's even on December 31, 1983, with the reason of a massive heart attack while he was 68 age at that time.

Dick Jahns was the oldest one among three children in his family, living with his father, Alfred H. Jahns and his mother, Cecelia (Schnackenbeck) Jahns. Before the first 11 years of his life, he lived in Los Angeles with his parents and two brothers, where is the place for the initiate of his railroad interest. When Dick was in age 11, the whole family moved to Seattle and stayed there for the next six years. In Seattle, the variety of marine near Puget Sound attracted him. As Dick's father was a ceramic engineer, Dick successfully acquired the knowledge and to be fascinated in Chemistry after he participated in his father's work. His high school grade let him pass the entrance examination of the California Institute of Technology smoothly which is in Los Angeles, and worked on the undergraduate programme in Chemistry in the college.

During the undergraduate programme, Dick had interest in sports, include track, basketball, as well as basebal l which was the top one that he preferred, and he explored the aspect of the railroad in deep simultaneously. At the third year of the college, Dick discovered that an outdoor career will be more suitable for him, and changed his degree into geology at the beginning of his senior years. Dick merely used one year to completed his undergraduate programme of geology successfully in the California Institute of Technology, while he was twenty. His enthusiasm of geology was demonstrated to his professor, Ian Campbell who provided a strong recommendation to Northwestern University that helped Dick obtained the availability for a graduate geology programme.

At the beginning of the summer following the graduation from the California Institute of Technology in 1935, Dick was invited as a member of a two-year programme for his Master's degrees. Dick met the best friend of his lifetime, Max Willard who was also a geology student, during the first year of the programme work. One year later, Dick married with his wife, Frances Hodapp that they met each other when Dick was in a junior in California Institute of Technology, and moved to Evanston to live. However, the barrier was that there was no enough apartment available for them, which let them have to share the apartment with Max and Max's wife. The problem did not solve until both Dick and Max received their Master's degrees in 1937.

Dick received a PhD candidate, while he chose to work in the United States Geological Survey (USGS) for $1,800 per year, and completed his PhD in 1943.

= Career =  Main Resource:   Memorial of Richard H. Jahns 

Dick Jahns was a teaching fellow in Northwestern University before he obtained the first job of his life. During the second year at Northwestern University, he passed the entrance examination of the United State Geological Survey (USGS) and worked in the Survey at the position in the Hydrology Branch for $1,800 per year, while he was a teaching fellow in the California institute Technology in 1937. The USGS sent a telegram to Dick and assigned him a new job in Nashua, New Hampshire. His new assignment was mapping every quarr y in New England, which motivated his consideration on the origins of granitic rocks, particularly pegmatite. The exploration of pegmatite was the critical focus of Dick's career. As the United States joined the World War I, according to the demand of World War I, Dick initiated a series of field study on the origin of mica, lithium and strontium.

During World War II, Dick and Frances traveled throughout the United State to observed and evaluate mica, beryllium, and tantalum. In this phase of Dick's career, he first arrived in New Mexico where is defined as the favorite state by the majority of people.

From 1940 to 1942, Dick served an assistant geologist and improved to an associate geologist in 1942 for the next two years. In 1943, Dick returned to the California Institute of Technology for the preparation of several strategic reports. After he completed his PhD, he was prompted as USGS District Supervisor with an assignment which represented evaluating the pegmatite deposits in the southeastern United States. Dick kept working on this programme for three years long. In 1944, Dick became a real geologist and continually working for Geology before his death. Dick kept working on Geological survey and became a senior geologist in 1949. During those year when Dick studied in Geology, he expanded the background of engineering geology, For example, he created maps of those landslide disaster areas such as Palos Verdes, while he did a research on late cainozoic volcanos which located in Pinnacle, Northwest of Sonora.

After the end of World War II, Dick decided to teach in a university, and finally chose to work in his Alma Mater, the California Institute Technology. Dick who as an assistant professor, initiated his 14 years of teaching career in the California Institute Technology. It took him only three years to be promoted from an associate professor to an official professor, and continue the study of origins granitic and pegmatite.

In 1960, Dick ended his 14 years teaching career in the California institute Technology and changed the working place to Pennsylvania State University as a professor of Geology and a chairman of Earth Sciences in the College of Mineral Industries for the next five years (1960 - 1965). Also, he joined a group which constituted by geologists and geochemists. After two years as a faculty in Pennsylvania State University, Dick was elected to be a Dean of the College of Mineral Industries. In 1965, Dick backed to California and accepted the position of Dean of the School of Earth Sciences and a professorship of Geology in Stanford University with the requirement from Fred Terman and Wallace Sterling. He served as dean of the School of Earth Sciences at Stanford University for 14 years long (1965- 1979). In 1979, Dick resigned as dean of the School of Earth Science but still to be a faculty of Geology and Applied Earth Science until his death. In addition, Dick even was a Master of Ceremonies for the 1975 AEG annual meeting which was held at South Lake Tahoe.

In Dick's later year, he also served as National lecturer Sigma Xi, and Member California State Mining and Geology Board from 1965 to 1975; Government's Science Advisory Board California and California Seismic Safety Commission from 1975 to 1983; Member of California desert conservation area advising committee United States Bureau Land Management from 1977 to 198; National Public Lands Advisory Council from 1979 to 1981.

Dick was a member of the board of directors of four California companies which were Lindvall, Richter and Associates, Earth Sciences Associates, and TERA Corporation.

Dick evaluated his entire career, claimed that "the most exciting and valuable aspect of teaching is seeing that young people who have been capable are active in intelligence; seeing a basic driving force in them".

= Connection = Dick married with Frances M. Hodapp on September 5, 1936 after his first year of MS degrees in Northwestern University. Their marriage lasted for 47 years until Dick's death. Dick's personalised license was written with "RHJ 36", which was the year that he and Frances married. They had two children, a daughter Jeannette Jahns and a son Alfred Jahns. Because of Dick's work which was in USGS, he and his wife Frances separated to live in New England and South California respectively. After that point. they made a decision that Frances went to New England to reunite with Dick and stay with him for the next career, although the policy of USGS was to not allow his wife to accompany with him at that time. In the first 11 years of their marriage, they set up housekeeping in 47 different places. After the outbreak of World War I, Dick signed a strategic minerals plan. During the war, Dick and his wife traveled around the United States to observed and evaluate for such things as mica, beryllium, and tantalum. After the end of World War II, Dick and his wife went to the West again and stay at the California Institute of Technology for 14 years, while their two children ware born.

During Dick's first year of MS degree, he met a geology student, Max Willard, and started a friendship which affected the remaining of his lifetime. in 1946 at the California Institute of Technology, Dick and an engineering student, Fredrick Converse, met a famous land developer, Barney R. Morris who were asking for help on the aspect of Geology in the California Institute of Technology. This meeting was the beginning of their intimate friendship.
