Dr. James Buckley ’50 was "the last of the Mohicans," as one former patient described him, a renowned family physician on the Peninsula cast from a classic mold. He often would treat three generations of the same family and made house calls in a 1960 VW Beetle with a spotlight for finding addresses after most doctors had stopped the practice, former patients said.  Dr. Buckley died peacefully at his Redwood City home on April 8. He was 82. Known for his quirky sense of humor, Dr. Buckley was also widely recognized for his uncanny ability to diagnose tough cases. "He must have got 50 calls a day from other doctors asking him to diagnose stuff," said Tim Alfred, a patient and friend of Dr. Buckley’s for more than 30 years. "He was unbelievably good."  Dr. Buckley was born June 21, 1927. He graduated from Bellarmine College Preparatory and served as a navigator in the U.S. Navy in 1945 before graduating in 1950 from Santa Clara University, where he played football on the team that won the 1950 Orange Bowl.  He graduated in 1953 from Stritch School of Medicine at Loyola University in Chicago, and married Winnie Brisbois the same year.  The couple raised 12 children in their Redwood City home.  Dr. Buckley established his practice in Belmont in 1959, joined the staff of Sequoia Hospital in Redwood City, and treated patients for 50 years. He was an adjunct professor for Stanford Medical School.  "I’m still here because he kept me going," said Gerald Colombi, 86, a patient for 35 years.
