Leonard Jacob, Jr., 91 years, of Kennebunk Beach, died Wednesday, July 21, 2021 at his home on Great Hill Road in the loving care of his family. He was predeceased by his wife of 64 years, Rita S. Jacob. Len was born March 20, 1930 in Boston, Massachusetts, son of Leonard and Eleanora (Winslow) Jacob. He attended St Paul's School and Williams College, where he excelled in the classroom and enjoyed playing hockey, baseball and squash. He was President of his Class at both schools and remained close with many of his classmates throughout his remarkable career and extraordinary life. Some of Len's fondest memories of his youth involved the summer road trips he took with his Williams classmates, to Texas, and to Washington State, looking for mining and geology-related jobs, only to end up picking strawberries or working a lumber camp. He and his buddies often packed their bags and headed home early, hitch-hiking back across the country and establishing important (as he told it) life-long learning experiences. Len later attended Columbia University where he attained his MA and his PHD in Geology. Following Columbia, Len was accepted to Naval Officer Candidate School and attended the U.S. Naval Post Graduate School in Monterey, California, where he received a degree in Advanced Studies in Meteorology. In 1955, he was promoted to Lieutenant and assigned to Fleet Weather Control in Sangley Point in the Philippines. On September 28, 1956, Len and Rita were married in Carmel, California, after which began a life-long adventure together, beginning with the 3-year stint in the Philippines. In 1959, Len was hired by Alcoa where he remained for over 25 years, establishing himself as one of the premier geologists and Managing Directors with international experience in the Raw Materials and the Exploration and Development divisions. Monterrey, Mexico was his first overseas assignment with Alcoa, followed by Cannes, France; Guinee, West Africa; and Parimaribo, Suriname, with stays at company Headquarters in Pittsburgh, Pennsylvania along the way. Len's success was attributable to his collaborative leadership style, his technical expertise, his respect for everyone he worked and interacted with, and for his patience and generosity, all so important in so many of the countries and cultures he called home over the years. Along the way, Len and Rita had five children born in three different countries. Most exciting for he and his family: in 1971, he assumed responsibility for the start-up and operation of a $400 million joint venture mining complex in Guinee, West Africa. As he wrote it: In the complicated environment of an underdeveloped nation struggling with post-colonial independence, this position required enormous versatility, imagination, and freedom to act. He loved Africa and he enjoyed the Expat lifestyle. In 1989, post-Alcoa, he assumed full management responsibility for Societe Miniere du Kivu, in the Democratic Republic of Congo. This was in the middle of what appeared to be nowhere. Len and Rita's home and the mining operation was a 6-hour Land-Rover trip from Goma, the nearest city. Len always said this assignment, and this part of the world, was his favorite. In 1981, while living in South America, Len and Rita purchased a home in Kennebunk Beach, Maine which became the family compound that the couple cherished and shared with so many friends and family over the years. In his free time, Len enjoyed playing tennis and squash, gardening (loved his dahlias), salt-water fishing, and, at the end of the day, relaxing on the front porch of his Kennebunk Beach house with his family and friends, and his favorite beverage of choice. He always looked forward to this time of day and spending time with his children, his daughter-in-law, his grand-children and close friends and family. One of Len's favorite books was "Blue Highways". The book chronicles the author's journey across the backroads of America (drawn in blue on old style maps) and the people he meets along the way. Len loved maps and appreciated the books' symbolism to life and maps. And he especially loved meeting and talking to people: family, friends, employees, strangers. Len was immensely generous, he had a heart of gold, and enjoyed sharing it with anyone and everyone. Leonard Jacob Jr. was predeceased by his wife Rita on November 29, 2020 and his sister Anita J. Hilton. Len is lovingly remembered by his daughter Sara and Sara’s husband, Claudio, of Johannesburg, South Africa; four sons: Leonard Jacob, III of Kennebunk, William Jacob and his wife, Martha, of Westport, MA, Robert Jacob of Scarborough, ME, and Peter Scott Jacob of Kennebunk; seven grandchildren, Julia, Malcolm, Alessandra, William, Noelle, Samuel and Nicholas. Due to the COVID-19 pandemic, services will be postponed until friends and family may gather safely. Should friends desire, memorial contributions may be made to Hospice of Southern Maine, 390 US -1, Scarborough ME 04074, In Mr. Jacob’s memory.
