Born in Segovia on October 31, 1910. Son of Manuel Ortiz de Landázuri García and Eulogia Fernández de Heredia y Gaztañaga. He was baptized on November 12 in the church of Santo Tomás. On May 5, 1917 he made his First Communion. He attended the high school diploma in Madrid (high school de los Padres Agustinos and high school Cardenal Cisneros) and Segovia (high school de teaching average ).

He had a very fond memory of Segovia, of the family atmosphere, of the military circles in which his parents moved and, as a consequence, of the walks and the Aqueduct, which was always a referential framework of his memories.

He studied medicine in Madrid, and licence in 1934. There he met Don Carlos Jiménez Díaz, teacher of several generations of Spanish physicians. In 1935 he joined the National Hospital of Infectious Diseases, and there he met his future wife.

In 1936 the civil war broke out, and on September 8 his father was shot in the prison model in Madrid. He remembers this event as "the most painful days of my life". The tragic death of his father had a decisive influence on him to rethink his whole life. He resumes the religious internship , which he had somewhat abandoned.

In 1940, he joined the Hospital Clínico de Madrid, together with Dr. Jiménez Díaz.

On June 17, 1941, he married Laura Busca Otaegui in Arántzazu. They met in 1935, at the Hospital del Rey, where she also worked, at department Pharmacy. They had seven children. His family -his wife and children- was the first field of service in his life.

He obtained his doctorate in 1944, and in 1946 he won the Chair of General Pathology of the School of Medicine of Cadiz, and by transfer, he obtained the same Chair in Granada. In 1951 is Dean of Medicine of Granada.

In 1952 he requested Admissions Office as a supernumerary in Opus Dei (this is the name given to the married faithful of Opus Dei, who live their Christian vocation to holiness through their profession and family and social life).

In 1958, being Vice President of the University of Granada, he proposed to his wife Laura to leave everything to start in Pamplona the School of Medicine of the Estudio General de Navarra, which would become in 1960 the University of Navarra. His life since then is linked to that University and to the University Clinic, where he will be Dean of Medicine and Vice President.
In October of that same year he moved to Pamplona, to join, as Full Professor of Pathology and Medical Clinic, the School of Medicine of the Estudio General de Navarra. He was also head of the Internal Medicine Department at the Hospital de Navarra.
He was Dean of the School of Medicine of the University of Navarra from 1962 to 1966 and from 1969 to 1978. From 1966 to 1969 he held the position of Vice President.
He was President of the association of Friends of the University of Navarra from 1978 until his death. He died on May 20, 1985.
He was in possession of the Health Cross, the Grand Cross of Alfonso X the Wise, and the Cross of Civil Merit of the Federal Republic of Germany. He was elected Collegiate of Honor of the high school of Doctors of Navarra in 1984. In 1985 he was awarded the award "Couder y Moratílla" of the Royal National Academy of Medicine.
He was director of the Centro de Investigaciones Metabólicas de Granada and of the Centro Coordinado de Investigaciones Médicas de Pamplona, advisor of the committee Superior de Investigaciones Científicas, member of the Spanish Society of Internal Medicine -of which he was president-, member of the Royal Society of Medicine of Great Britain, and of the French Society of Gastroenterology, honorary member of the association Argentina de Farmacología y Terapéutica Ex- perimental, and academician of issue of the Academy of Medicine of Granada.

In his fifty years of medical activity -since he finished his programs of study- at the National Hospital, the Prison Doctors Corps, the San Carlos Clinical Hospital, the General Hospital of Madrid, the Hospitals of San Juan de Dios, San Lázaro and San Cecilio in Granada, the Hospital of Navarra, the Virgen del Camino Health Care Center of the Social Security, and the University Clinic of Navarra, and in his private practices in Madrid and Granada, approximately five hundred thousand patients passed through his hands.

Those of us who have known him and shared our day to day work at CUN for eleven years - as is my case - can affirm that he was a person who transmitted a deep peace and joy, the fruit of a simple and strong Christian piety.

His professional activity reached a surprising intensity: workshop began very early in the morning and usually ended in the early hours of the following day. Every day he went to Mass at eight o'clock in the morning at the Clinic, not without first dedicating average hour to prayer. He used to help the priest at the celebration; he was very excited about it, he looked like a child. The other people who usually attended that Mass already knew how much he was looking forward to it; that is why no one else came forward. He did so until he fell ill. He attended to his colleagues and collaborators with application ; for the students he was a teacher and guide, both professionally and humanly. He treated each one with affability and always tried to be available; at the same time, he was demanding with himself and with others, because he wanted to make the talents he had received work for God. The students found in him a true friend, because he was interested in all the human facets of people, to help them improve both physically and spiritually.

A few years ago I heard Don Eduardo express an opinion that puzzled me at the time and that today seems obvious to me and the fruit of a very rich inner personality: "Doctors," he said, "are not veterinarians. And we are not for a simple reason: because they take care of animals and we take care of rational animals".

He then drew this consequence: "I am so aware of this that I never forget it when I ask questions to guide me in my diagnoses. That explains why I have often had to say to a sick person: "Go home, make peace with your wife and stop taking pills; because your illness (stomach pain, anxiety, pre-cordial pain, professional rejection, etc.) is in the soul, not in the body".

On more than a few occasions," he concluded, "they listened to me and after a while they came back to thank me for such a simple and effective remedy.

In 1983, he left teaching at the age of 73. Shortly thereafter, he was diagnosed with a cancerous tumor. When he underwent surgery, it was discovered that the cancer was incurable because it was so widespread. From the first moment he was aware of the seriousness of his illness and accepted it, uniting himself more and more to the sufferings of Christ on the Cross, for the Church. His last two years of life were still filled with great professional activity, full of eagerness to bring many souls closer to God.

On May 1, 1985, he was definitively admitted to the University Clinic of Pamplona, witness of his infinite devotion to the sick. On the morning of May 19, 1985, Sunday, Solemnity of the Ascension of the Lord, I had the privilege of celebrating Holy Mass in room 301, on the eve of submit his soul to God. On May 20, 1985, he died at 9:10 a.m. at the University Clinic of Navarra, witness of his infinite devotion to the sick, after having piously received the Holy Sacraments, while repeating this prayer: "Lord, increase my faith, increase my hope, increase my charity, so that my heart may resemble yours! I want to go to Heaven. Yes, I believe in Heaven. The place where I will enjoy the contemplation of God".

Shortly before, he had confided with simplicity to his spiritual director : "I believe that I have fulfilled my mission statement in this life and that the Lord will not be very dissatisfied with me. Now my mission statement is to die well, with much peace and much joy".
From that moment on, the fame of her holiness, which many already appreciated in her life, was manifested and every day more and more people trust in her intercession before God.

On December 11, 1998, having completed the necessary formalities, the Archbishop of Pamplona decreed the Introduction of the Cause of Canonization and the First Session of the Diocesan Process of his Life, Virtues and Fame of sanctity took place. The entire diocesan research ended on May 28, 2002 and immediately the authentic copy was sent to the Congregation for the Causes of Saints.

May the words of this egregious Segovian come true in our lives: "Everything I have done in my life, in all areas, I have done it with love!
