Faculty and staff at the LSU Health Sciences Center in Shreveport -- indeed, the whole community -- is mourning the death of the health complex's first chancellor. Doctor John McDonald died early Saturday at his Shreveport home. He was 81 years old. The noted transplant surgeon served as chancellor from 2000 until his retirement in 2008. In all, he spent more than three decades at the LSU Health Complex. Doctor McDonald's family will receive visitors from 4 until 7 tomorrow at Rose-Neath Marshall Street and from 2 until 3 Thursday in the first floor auditorium at the LSU Medical School. A memorial service will be held in that auditorium at 3 Thursday afternoon.
