Allen said Kohler, a graduate of Pennsylvania's Slippery Rock College, was a Pittsburgh Steelers fan and an avid, though not overly skilled, golfer.
"He could probably shoot in the low 90s," Allen said in a telephone interview Tuesday from Bradenton, Fla. When Allen retired, Kohler picked his gift — a gold pocket watch with the inscription, "From your friends in Lockheed Martin to help you putt into the future."
Kohler lived on the water with his wife, Michelle, an employee at the Naval Air Station Patuxent River. Allen said his friend loved to boat and fish, and went on frequent hunting trips to Canada.
"A great family man, a Christian, and a great friend," he said. "It just doesn't seem possible. I mean, you hear about these things all the time ... But when you know somebody, it just makes it all the worse ... It's a Huge loss for southern Maryland."
Marine engineer and naval architect Vishnu Pandit, 61, preferred the nickname Kisan, the Hindi word for "peasant." It suited the hard-working Indian immigrant, known for his devotion to family, community and his 30-year civilian Navy career.
"He was very dedicated to improving the performance of naval ships and systems," longtime friend M. Nuns Jain said Tuesday outside the North Potomac home where Pandit's family privately mourned. "The only saving grace in this horrible incident is that he died doing what he loved the most in the service of his nation."
Jain said Pandit, a Mumbai native, earned a bachelor's degree in marine engineering in India in 1973 before coming to America and receiving a degree in naval architecture from the University of Michigan.
He said Pandit sailed with the U.S. Merchant Marine before joining the Naval Sea Systems Command, headquartered at the Washington Navy Yard.
Married to his wife Anjali since 1978, Pandit had two sons and a granddaughter, Jain said.
