Emery W. "Ted" TetraultNSA Linguist

Emery Wilfred "Ted" Tetrault, 75, a linguist and foreign language teacher for the National Security Agency, died Feb. 8 of complications of Alzheimer's disease at Lewes Convalescent Center in Lewes, Del. He lived in Rockville and Rehoboth Beach, Del.

Mr. Tetrault was born in Worcester, Mass. He graduated from Assumption College in Worcester in 1952. He served in the Air Force from 1952 to 1956; he was stationed in Korea and learned Russian at the Defense Language Institute in Monterey, Calif. He also was fluent in French and was conversant in several other languages. He received a master's degree in linguistics from American University in 1970.

He joined the NSA in 1956. Among relatives and friends, he was Ted, his son recalled, but at work, he was "Tet" -- "like the offensive," he would joke.

An applied linguist, Mr. Tetrault was instrumental in developing many of the federal government's foreign language teaching programs at the National Cryptologic School and was a nationally recognized expert in adult language learning, teaching methodologies and translation. Teaching was his love.

A longtime friend and NSA colleague noted that Mr. Tetrault's pedagogical techniques became standard practice at the Interagency Language Roundtable, the organization that helps coordinate language training at the Defense Language Institute, the Central Intelligence Agency, the Federal Bureau of Investigation and other federal agencies. He also advised language programs at colleges and universities around the country.

His awards included the Meritorious Civilian Service Award in 1983; the National Intelligence Medal of Achievement in 1992; the Sydney Jaffee Award, for "unparalleled achievements in the field of cryptologic linguistics," in 1992; and the Cryptologic Service Award, also in 1992. He retired in 1996.

Survivors include his wife of 50 years, Joan Helen Tetrault of Rehoboth Beach; five children, William Tetrault of Brooklyn, N.Y., Joseph Tetrault of Baltimore, Theresa Moller of Washington, Robert Tetrault of Rockville and Julie Tetrault of Rockville; and four grandchildren.

Pierre Hyacinth Conway, 90, a Dominican priest and scholar of Thomas Aquinas, the Catholic theologian and saint, died Jan. 23 at the Dominican House of Studies in Washington. He had a heart ailment.

The Rev. Conway was born Eugene Scanlan Pierik Conway in Forest Hills, N.Y. After his mother died in the flu pandemic of 1918, he lived with relatives in Chicago and Canada. During his youth, he excelled at ice hockey and cycling.

A maternal aunt, formerly with a French Dominican convent, decided he should have a French classical education in Europe. He graduated from the University of Paris before joining the Dominican order in 1934.

The order gave him the religious name "Hyacinth" after the Polish Dominican saint of the 13th century. He was ordained at St. Dominic parish in Washington in 1941 and received a doctorate in philosophy from Laval University in Quebec in 1946.

Around that time, he became involved in the Catholic Worker Movement through its founders, Dorothy Day and Peter Maurin. Maurin, who died in 1949, was buried in the Rev. Conway's family plot.

The Rev. Conway preached to the poor at Catholic Worker houses, taught philosophy at colleges from Rhode Island to Rome and spent six years as a parish priest in Jersey City.

Fluent in Latin and French, he also was assigned to the Dominican House of Studies in Washington from 1957 to 1962 to do writing and translating of Latin texts.

He returned to the Dominican House in 1979, adding to his duties the function of guestmaster and ministering to those in need of counseling, food and money.

From 1989 to 2005, he was chaplain and spiritual director of the Immaculate Conception Chapter of the Third Order of Preachers, a branch of the Dominican Order that meets at the Dominican House.

His books included "Principles of Education: A Thomistic Approach" (1960). He also published in religious journals, translated works of Aquinas and was outspoken in favor of adoption over abortion.

Survivors include a brother, John K. Conway of Dallas.

William Malcolm Logan, 61, a retired Department of Justice attorney, died of an acute subdural hematoma Jan. 28 at Georgetown University Hospital. He lived in Takoma Park.

Mr. Logan worked at the Justice Department from 1972 until 1996, in the civil rights and tax divisions. He also was an assistant U.S. attorney in Anchorage.

Born in San Antonio, he grew up in Kerrville and Austin. He graduated from the University of Texas and received a degree from its law school in 1969. He served in the Navy and then worked for the old Department of Housing and Urban Development before moving to the Justice Department. He retired in 1996.

Survivors include his wife, Roberta Dale Kimball of Takoma Park; three brothers; and a sister.

James Frank De Deo, 63, a civil litigator who was a partner in the Fairfax City firm Moshos, Byrd, McClure, McWeeny and De Deo from the mid-1970s until 1999, died of cardiac arrest Feb. 12 at Reston Hospital Center. He had heart disease.

Mr. De Deo was born in Newark and graduated from Roanoke College, which he attended on a track scholarship. He was a 1969 graduate of American University law school and was director of Legal Aid in Fairfax County in the early 1970s.

A Vienna resident, he coached his children's soccer teams and enjoyed biking, kayaking, camping and hiking mountains in Ecuador with his son.

Survivors include his wife of 34 years, Carol Greenlief De Deo of Vienna; two children, Elinor De Deo of Arlington and Daniel De Deo of San Francisco; and two sisters.
