DEATHS
ASNT Lifetime member Dr. Borislav (B.)
Boro Djordjevic died on 26 November
2023 at Mercy Hospital in Baltimore,
Maryland. He was born on 25 August
1951 in Brežice, Yugoslavia, and immi-
grated to the US in 1968, residing in
Williamsburg and became a US citizen in
1976. He attended the College of William
&Mary where he graduated with a BS in
Physics in 1973. He continued to pursue
his education at Johns Hopkins University,
earning both his MSE in mechanical and
materials engineering (1978) and his PhD
in materials science (1979).
Djordjevic leaves behind an impres-
sive legacy of academic and industrial
accomplishments. He contributed heavily
to the aerospace industry including work
for the NASA space shuttle program. He
returned to academia for a time at his
alma mater Johns Hopkins to serve as
Director of the Center for Nondestructive
Evaluation to mentor and guide future
generations of engineers and world-
changers. He began his own consulting
company, MAST Inc., to continue advising
and offering consultation work, even
after his formal retirement. During his
career at Martin Marietta Laboratories,
Djordjevic received an Outstanding
Achievement Award in 1983 and 1984.
He was also the recipient of the Martin
Marietta Jefferson Cup in 1984, the corpo-
ration’s highest award for outstanding
technical achievement. He later received
the Research Award for Sustained
Excellence from ASNT in 2014 and the
Robert C. McMaster Gold Medal in
2021. In April 2020, he was recognized
by Marquis Who’s Who with the Albert
Nelson Marquis Lifetime Achievement
Award. Djordjevic was very involved in
ASNT’s councils and committees. He
was also a reviewer and contributor for
many of ASNT’s publications including the
Ultrasonic Testing Handbook and served
as an ATE for Research in Nondestructive
Evaluation.
ASNT Fellow Don E. Childers died on
9 November 2023 after a long illness.
He was 86. Childers joined the Navy in
August 1954 and proudly served aboard
the Navy destroyer, The USS Halsey Powell
(DD 686), based out of Long Beach,
California. He received a China Service
Medal for his service in the Pacific during
those years. In 1967 Childers went to
work at the NASA facility in Clear Lake
City, Texas, and it was there that Childers
started his long, much-loved career in
the field of NDT. It was an interesting and
exciting time to be involved in the space
industry. In the 1970s, Childers went to
work for Southwestern Laboratories,
an engineering and NDT company in
Houston. After several years there, he
went to work for Metco/Mistras Group
and served as their NDT Corporate
Level III for several years. He was a
consultant and taught NDT methods
for several companies in the Greater
Houston area, Montgomery County, and
the Montgomery County Community
College. He was a member of the Greater
Houston Section of ASNT. Childers and
his wife, Patricia, were early supporters
of both ASNT and the Houston Section,
and watched the Society grow to be
what it is today.
