Paul (1925–2005) was a photographer and model airplane distributor who was an Army projectionist in WWII. Tim assisted in the photography and shop work. Margaret was born in 1929 and died in 1996. His mother talked him into watching an annual television broadcast of ''

Samaras attended Lasley Elementary and O'Connell Junior High in Lakewood, before graduating from
Alameda International Junior/Senior High School in 1976.
In his twenties, he began to chase storms "not for the thrill, but the science."
He would continue this pursuit until his untimely death in 2013.

In total, he tracked down more than 125 tornadoes during his career.

all of which combined so that several other chasers were also hit or had near misses. It was the first known instance of a storm chaser or a meteorologist killed by a tornado.
Even before it was known that Samaras, his son, and Young had been killed, the event led many to question storm chasing tactics, particularly in close proximity to tornadoes. In addition to the three TWISTEX members, the tornado killed five other people, including local resident Richard Charles Henderson who decided to follow the storm.

Meteorologist
Jim Cantore remarked "This is a very sad day for the meteorological community and the families of our friends lost. Tim Samaras was a pioneer and great man."
''National Geographic'' remarked "Tim was a courageous and brilliant scientist who fearlessly pursued tornadoes and lightning in the field in an effort to better understand these phenomena."

Personal life
Samaras and his wife Kathy had three children — Paul (November 12, 1988 – May 31, 2013), Amy Gregg, and Jennifer Samaras.
The family lived on 35 acres near
Bennett, Colorado, at the time of his death.
The open space enabled Tim to erect amateur radio and other towers and provided ample room for workshops. He learned of the property through real estate investment work that he did on the side and to which his brother Jim introduced him.
Samaras had another son, Matt Winter, whom he had only learned about seven years before Samaras' death and who was welcomed into the family. Winter was also fascinated by weather and was informed by his mother that Tim was his father after he heard Samaras speak at the 2006 Severe Storms and Doppler Radar Conference in
